Power Modules Get Through, But Think Before Choosing

Power modules will come in your mind first when it is about leveraging the knowledge of the power specialists and bringing your model to the market promptly, but think before choosing. Power-module architecture selections can have an significant impact on the performance of your power supply.

Either judging step-down switching regulators at the silicon-level (moderator with FET), or power modules where the consolidation, and effortlessness of usage of a further accomplished power supply subsystem can be preferable, system makers are under immense pressure in all over the world. Though the form factors are being curtailed day by day, the system designers are being assigned with amalgamating more power and features. System’s electrical and thermal characteristics are being affected adversely by this.

To integrate nirvana, the system designers must have to overcome several obstacles. Increased possibility of noise coupling is included to these. This is very likely to occur as components are in close proximity, as well as heat wastage, given that the power-handling capabilities continue to rise along with lesser footprint areas.

Luckily, power module designers resume to introduce new ideas to fulfill these challenging demands with the help of different architectural and topological design techniques those extract the utmost performance from the smallest package. Still, these innovations put the burden on the system designers in need of the perfect power module to be cautious in their option of solutions. The methods used by various power module solutions may comprehensively have an effect on total system cost, as well as primary performance parameters such as heat dissipation, transient response, ripple voltage, and even ease of use. It’s a great instance of ‘buyer beware’.

Modular versus Discrete case

For system designers, there are many causes to choose for a power module against designing a power converter from the component level, not least of which are ease of use and time-to-market. By attaching input and output capacitors only, these power customers can finish their designs comparatively simply and rapidly, with confidence that their primary performance and space necessities have been met. The power module is a total power converter system in an encapsulated combination that comprehends a PWM controller, simultaneous switching MOSFETs, inductors and passive components.

Fuji IGBT in CNC Machines

Numerical control (NC) is the mechanization of machine tools that are functioned by accurately programmed commands encoded on a storage mean, as against to run manually via hand wheels or levers, or mechanically automated via cams alone. Most NCs today are computer numerical control (CNC), in which computers play an integral part of the control.

Fuji Electric delivers high-performance power semiconductors for energy, automotive, information technology, and industrial applications. IGBTs (Insulated Gate Bipolar Transistor) made my Fuji is used widely in CNC plasma cutters and welding machines.

Plasma cutting involves cutting a material using a plasma torch. It is commonly used to cut steel and other metals, but can be used on a variety of materials. In this process, gas (such as compressed air) is blown at high speed out of a nozzle; at the same time an electrical arc is formed through that gas from the nozzle to the surface being cut, turning some of that gas to plasma. The plasma is enough heated to melt the material being cut and moves pretty fast to blow molten metal away from the cut.

Arc and tube welding machines are mostly used in industrial setting for building and repair of the infrastructure. Welding power supplies are required to create an electric arc between an electrode and the base material to melt the metals at the welding point. The arc can be created by either DC or AC current with consumable or non-consumable electrodes. The welding region is sometimes protected by some type of inert or semi-inert gas.

Arc welding is popular due to low capital and running costs. For arc welding, the voltage is directly related to the length of the arc, and the current is related to the amount of heat input with typical currents of 50 to 500 amps depending on the size of weld. For arc welding with low voltages and large currents, a soft switching PWM DC-DC power converter with Fuji IGBT switches in the primary side of a high frequency transformer is considered to be the most suitable topology for the welding power supply110, 111. Power losses in the Fuji IGBTs are reduced by using soft switching resulting in a volume reduction of 59% and weight reduction of 47% compared with the hard-switching approach. Dynamic welding performance is improved due to operation at 40-kHz when compared with 13-kHz with hard-switching.

FPGA Design & Programming and Comparison to ASIC

A schematic design or a hardware description language (HDL) is provided by the user to define the behavior of the FPGA. The HDL form should be used to work with huge structures because it is feasible to exactly specify them by numbers rather than having to draw every piece manually. On the other hand, simpler visualization of a design is the main advantage of schematic entry.

Then, utilizing an electronic design automation tool, a technology-mapped netlist is created. The netlist can then be fitted to the real FPGA architecture using a method called place-and-route, usually executed by the FPGA Company’s proprietary place-and-route software. The user will validate the map, place and route results via timing analysis, simulation, and other verification methodologies. Once the design and validation process is done, the binary file generated (also using the FPGA company's proprietary software) is used to (re)configure the FPGA. This file is shifted to the FPGA/CPLD via a serial interface (JTAG) or to an external memory device.

VHDL and Verilog are the most common HDLs, though in order to minimize the complexity of designing in HDLs, which are in comparison to the equiponderant to the assembly languages, there are steps to increase the abstractiveness level through the introduction of substitute languages. For targeting and programming FPGA hardware, an FPGA add-in module is available to National Instruments' LabVIEW graphical programming language (sometimes referred to as "G").

Formerly, FPGAs (Field programmable Gate Array) lagged behind than their rigid ASIC (Application-specific integrated circuit) peers in terms of operational speed, energy efficiency and overall functionality. It was demonstrated by an older research that designs executed on FPGAs require on an average 40 times as much area, pull 12 times as much dynamic power, and achieve one third the speed of resembling ASIC executions. In the modern days, FPGAs like Virtex-7 from Xilinx or Stratix 5 from Altera have taken place to contend with resembling ASIC and ASSP solutions by providing notably minimized power, extended speed, and decreased cost of materials, least execution real-estate and expanded likelihood for re-configuration 'on-the-fly'. A design can now be attained using just one FPGA where 6-10 ASIC may have been used in the same design in the past.

Conveniences of FPGAs comprise the facility to reprogram in the area to fix bugs, and can comprise a briefer time for marketing and lesser non-recurring engineering expenses. A moderate road can be taken by the vendors by developing their hardware on common FPGAs, but manufacture their ultimate version as an ASIC. As a result of this, it cannot be modified any longer after the design has been implemented.

Specified uses of FPGAs comprise ASIC prototyping, digital signal processing, computer hardware emulation, software-defined radio, medical imaging, bioinformatics, computer vision, speech identification, cryptography, metal detection, radio astronomy and an increasing extent of other areas.

In the beginning, FPGAs started as challengers to CPLDs and contended in an analogous space, that of glue logic for PCBs. As their size, capacity, and speed enhanced, they started to takeover bigger and bigger functions to the point where few are now marketed as complete systems on chips (SoC). Especially with the launch of dedicated multipliers into FPGA architectures in the late 1990s, applications which had conventionally been the only reserve of DSPs started to incorporate FPGAs instead.

One more tendency on the usage of FPGAs is hardware acceleration, where one can use the FPGA to accelerate particular parts of an algorithm and share part of the computation between the FPGA and a general processor.

IGBT Inverters in UPS



The most effective way to save electronic equipments from power problems is using UPS. UPS units have different sizes, from little desktop system that shields an individual PC to massive UPS that can supply power to a whole building. Nearly every organization has a power safeguard necessity, ranging from companies with computer UPS provides power to your equipment in the case of a entire power collapse, giving you opportunity to save data and close files. At a more commencing level, the UPS conditions and filters networks to hospitals, airports, oil rigs and anywhere where uninterrupted power is must. Today maximum industries are using UPS to save their core business against mains failures, mains supply fluctuations, power surges, and other troubles in the electrical supply. Spontaneous control, outstanding switching features and excellent reliability make IGBTs the perfect option today for medium and high-power UPS. These modules greatly enhance UPS performance, specifically in terms of proficiency, acoustic noise, shaped and weight. In high capacity UPS where the inverter functions between 2 and 4 kHz, the prime benefit of the IGBT is simplification of transistor control (better reliableness). IGBT is comparable to the bipolar transistors in terms of efficiency.



Manufacturers are using IGBT based motor drives in CT machines

http://uscomponent.com/blog-preview.php?postid=30


State-of-the-art medical diagnostic equipment has transformed the quality of care for our society. Non-invasive imaging of the interior of the body enables the surgeon to perform operations while minimizing damage to adjacent tissue and organs. The IGBT has been used since the early deployment of CT scanners for the control of the gantry on which the patient is reclining as described below. It is also used in the power supply for X-ray and Ultrasound machines. In addition, hundreds of thousands of lives are being saved due to the availability of portable defibrillators which require IGBTs for delivering the controlled shock to the patient of cardiac arrest as discussed below. Computed tomography (CT) generates a three dimensional image of a patient using a large series of two dimensional images taken around a single axis of rotation. The image is generated by viewing the patient using x-ray imaging from numerous angles. A single plane of a patient is scanned from various angles in order to provide a cross-sectional image of the internal structure of that plane. A three-dimensional view can then be created by mathematical analysis that combines the images. The gantry on which the patient is reclining is positioned using closed loop feedback control of motors in order to accurately move and position the patient. An IGBT-based motor drive is employed by all manufacturers, such as GE, Philips, and Siemens, for precise and controlled movement of the gantry. The CT scanner contains an X-ray tube with detectors located diametrically opposite the X-ray source which are rotated around the patient to generate a section image. CT scanners can provide detailed cross-sectional images of nearly every part of the human body including the brain, neck, shoulders, cervical spine, heart, lungs, abdomen, liver, kidney, pelvis, etc.

IGBT-based Motor Drives in Public Transports

The IGBT has a major impact on the transportation sector in all over the world. It enabled the introduction of cost effective and reliable electronic ignitions systems that have improved gasoline fuel efficiency by at least 10 percent. They have also been critical elements in the improvement of mass transit systems and the deployment of electric and hybrid electric vehicles. Modern mass transit systems rely up on electric trains where the propulsion is derived from supplying AC power to motors. High speed rail, such as the European TGV and the Japanese Shinkansen bullet trains allows travel by large numbers of people while avoiding fossil fuel consumption experienced with gasoline powered automobiles and aircraft. Until the 1990s, the silicon GTO was the only available power semiconductor switching device with the power handling capability suitable for this application. In the 1990s, the ratings of IGBTs had sufficiently advanced, to exceed one Mega-Watt allowing penetration of the IGBT into this traction market. The availability of the IGBT allowed significant improvements in the motor drive technology due to elimination of snubber circuits and an increase in the operating frequency of the inverter circuit used to deliver power to the motors. Mass transit systems within cities must rely upon a busses, trams, and underground trains. Many cities have been replacing gasoline powered busses with electric busses and trams to reduce urban pollution. All of these below requirements were met by using the IGBT-based motor drive in control system for the electric transit bus: (a) wide range of speed including high operating speed; (b) large startup torque for good acceleration; (c) high efficiency; and (d) regenerative braking to increase utilization of batteries. In Europe and Japan, electric tram transit systems have been modernized by using IGBT-based motor drives. According to AEG-Westinghouse Transport Systeme, Germany, the low floor concept is becoming a standard customer prerequisite. This has been enabled by today’s IGBT modules.

Calentamiento excesivo de los IGBT y como evitarlos

Un aumento excesivo o inesperado de la temperatura interna puede conducir a la evaporación del agua ya la pérdida de refrigerantes en los sistemas críticos de enfriamiento de la turbina, y eventualmente puede causar que la electrónica de la turbina se sobrecaliente. Esto es una preocupación particular en las máquinas con un sistema de refrigeración de lazo abierto y puede ocurrir incluso con el uso de refrigerantes de alta calidad. Un sistema de bucle abierto permite que el agua se evapore gradualmente desde el refrigerante de agua-glicol en el circuito de transistor bipolar de puerta aislada (IGBT), particularmente durante el tiempo cálido. (Los IGBT son un componente electrónico utilizado típicamente en turbinas debido a sus capacidades de conmutación rápidas y eficientes.) Un problema puede ocurrir cuando la evaporación del agua disminuye el nivel del refrigerante y eleva la concentración de la mezcla. Si el sistema se deja sin control y no se mantiene, el desequilibrio de mezcla resultante inhibe las propiedades de enfriamiento del fluido. Esto potencialmente compromete el IGBT. Huelga decir que una pérdida de componentes IGBT debido al sobrecalentamiento puede resultar en costosas pérdidas de hardware y un tiempo de inactividad significativo de la turbina. Para evitar esto, los operadores de viento han "vendado" el problema con una cadencia regular de monitoreo de refrigerante, reposición de agua y reequilibrio de la mezcla de fluido refrigerante. Este enfoque puede funcionar cuando se respeta diligentemente, pero es un costoso plan de mantenimiento. Requiere tomar la turbina y el transformador fuera de línea, lo que también significa tiempo de inactividad de la turbina y pérdida de ingresos para el parque eólico.

El crecimiento de los transistores de potencia regresa después de un período volátil, según IC Insights

Desde la recesión de semiconductores de 2009 y el fuerte año de recuperación de 2010, las ventas de transistores de potencia se han visto afectadas por la volatilidad del mercado, disminuyendo en tres de los últimos cinco años debido a las correcciones de inventario y las reducciones de los fabricantes de sistemas preocupados por la debilidad económica y la erosión de precios en algunas categorías de productos. Tras recuperarse de una caída del 7% en 2015, las ventas de transistores de energía crecieron un 5% en 2016 a US $ 12.900 millones y se pronostica que alcanzarán un récord récord este año, con ingresos mundiales creciendo un 6% a US $ 13.600 millones. El esperado crecimiento de 2017 en las ventas de transistores de potencia será el primer incremento anual consecutivo en este segmento de mercado de semiconductores en seis años, y eso empujará los volúmenes de dólares más allá del récord récord de US $ 13,5 mil millones establecido en 2011, IC Insights dijo . En 2012 y 2013, los transistores de energía sufrieron su primera caída de ventas anuales consecutivas en más de tres décadas -cabeza del 8% y 6%, respectivamente- después de subir un 12% en 2011 y un aumento del 44% en la recuperación de 2010 respecto del 2009 año de recesión. El mercado de transistores de potencia se recuperó luego en 2014 con un fuerte aumento del 14%, sólo para caer un 7% en 2015. En 2016, esta categoría de mercado de semiconductores discretes comenzó a estabilizarse y se espera que continúe expandiéndose a un ritmo modesto en los próximos años, IC Insights indicado. Sin embargo, la volatilidad en la primera mitad de esta década dio lugar a una caída inusitada en el tamaño del mercado de los transistores de potencia durante los últimos cinco años, IC Insights señaló. Entre 2011 y 2016, las ventas de transistores de potencia cayeron por una tasa de crecimiento anual compuesto de 0,9% negativo, comparado con un incremento medio anual histórico de 25 años de 6,4% (entre 1991 y 2016). IC Insights pronosticó que las ventas mundiales de transistores de energía aumentarán en un CAGR del 4,2% entre 2016 y 2021, llegando a US $ 15,8 mil millones en el último año del pronóstico.

CONSOLIDACIÓN EN LA INDUSTRIA

Aunque el segmento de potencia discreta y módulo es un mercado maduro, es dominado hoy por Infineon, que tiene dos veces los ingresos del segundo fabricante de estos productos, dijo el Dr. Pierric Gueguen, gerente de unidad de negocios, Yole Développement. "En este mercado, esta posición no es adecuada a largo plazo. Esperamos que el mercado continúe consolidándose para obtener más activos para competir con el líder del mercado. La adquisición de IXYS es un ejemplo, así como la adquisición de Fairchild por ON Semiconductor el año pasado ". "Con la adquisición de IXYS, Littelfuse confirma su presencia y posición como proveedor de IGBT", agregó Gueguen. "Littelfuse se beneficiará de los diseños de dispositivos IXYS y conocimientos de empaquetado de módulos, así como una sólida cartera de patentes para acelerar su desarrollo tecnológico y sus ingresos". Antes de la adquisición de IXYS, Littelfuse adquirió la línea de productos IGBT de ON Semiconductor en septiembre de 2016. El negocio generó menos de $ 25 millones en ingresos en el año fiscal de 2015. La mayoría de los jugadores de IGBT ofrecen soluciones discretas y de módulos en el rango de voltaje medio de 600V a 1300V, que representa más del 60 por ciento del mercado mundial de IGBT, dijo Yole.
