Exchanging it up - IGBTs

An Insulated Gate BipolarTransistor (IGBT) is a key part of what makes up a VFD (Variable Frequency Drive). In the event that you separate a VFD, one simple approach to break down it is to consider it in three principle parts: the scaffold converter, DC join, and what we will discuss today, the inverter. An IGBT is the inverter component in a VFD, beating voltage quicker than we can even squint.

IGBTs have made some amazing progress since they were initially created in the 1980's. The IGBTs of today are considerably more progressed than their antecedents, which were moderate at exchanging current on and off and frequently had issues overheating when passing a high present. With each new era, IGBTs have kept on making strides. No more tormented by moderate rates, IGBTs have turned out to be exceptionally solid gadgets that can deal with high voltage gadgets and can switch in under a nanosecond (that is a billionth of a second)!

IGBTs are the "Watchmen" of Current

To comprehend an IGBT's part in a VFD, it is imperative to recognize how an IGBT takes a shot at a littler scale. As characterized by being a transistor, an IGBT is a semiconductor with three terminals which function as a switch for moving electrical current. Generally as "entryway" proposes, when the voltage is connected to the door, it opens or "turns on" and makes a way for current to stream between the layers. On the off chance that no voltage is connected to the door, or if the voltage is not sufficiently high, the entryway stays shut and there will be no stream of power. Along these lines, an IGBT acts like a switch; on when the entryway is open and streaming present and off when it is shut.

In this way, the IGBT acts as the switch used to create Pulse-Width Modulation (PWM). An IGBT will switch the current on and off so rapidly that less voltage will be channeled to the motor, helping to create the PWM wave. For example, although the input voltage may, in reality, be 650V, the motor perceives it as more like 480V by using PWM (shown in diagrams below). This PWM wave is key to a VFDs operation because it is the variable voltage and frequency created by the PWM wave that will allow a VFD to control the speed of the motor. Therefore, without the IGBT switching the current on and off so rapidly a PWM wave—and the speed control that comes with it— could not be created.

The number of pulses per second from the IGBTs is known as a carrier frequency. Since carrier frequency is an adjustable parameter on most VFDs, you can essentially set it as high or as low as you want. Although, adjusting the carrier frequency comes with a few tradeoffs. Setting the carrier frequency too high will reduce the acoustic noise level produced from the VFD, but it will also shorten the expected VFD life due to heat. A higher carrier frequency will also contribute to an increase in motor heating and affect the overall efficiency of the motor. On the other hand, if you are in a sound sensitive environment – or if you just don’t want a headache – setting the carrier frequency too low can create a lot of motor noise or whining from the VFD. We have found that setting your carrier frequency at about 2 Kilohertz will achieve a nice balance between the audible acoustics while still keeping your VFD running efficiently.

In a typical six pulse drive, there is six IGBTs pulsing voltage up to 15,000 times per second. Since their introduction in the 1980’s, IGBTs have literally switched up the market and now play a large role in many modern day power electronics applications where speed and process control are needed. It is clear that IGBTs play a large role in many power electronic applications and will continue to as they become more and more advanced in their technology. Hopefully taking this in-depth look at the small part an IGBT plays has helped you to understand the overall functionality of a VFD as well.

Diferencias entre un transistor de efecto de campo de puerta aislada (MOSFET GATE) y el transistor Bipolar de Puerta Aislada (IGBT GATE)

Asumiendo el punto de interés es la potencia MOSFETS  y no  las pequeñas señales  MOSFET y silicio (lo contrario  a SIC, GAN).

Hay que estar atentos  que algunos  IGBT drivers  también tienen la opción de desactivar la tensión (para que los cambios sean más rápidos).

La primera característica que tenemos que chequear es la tensión de salida. Para los dispositivos de potencia deben de ser 0V a 12-15V (acpl-312T)  para atender a los umbrales de puerta alrededor 4V (Además de ser capaz de conducir a 15V Si activación de miller es una preocupación).

Tal como un Driver MOSFET conduciendo un IGBT e igualmente un driver IGBT conducir un MOSFET debe de estar bien.

La siguiente característica debe tener una corriente máxima. IGBT tendrá significantemente  una mayor capacidad  de puerta y como tal requiere mayores corrientes de pico para asegurar que el dispositivo se satura tan rápido como sea posible. Lo contrario a esto sería que los  MOSFETS se puedan cambiar más rápido y como tal la actual demanda de rms de conducir  un MOSFET podría ser más alta.

La corriente más alta  o cambios más altos de frecuencia afecta la potencia de la capacidad de los Drivers.

IGBT En El Sector De Generación De Energía De Combustibles Fósiles

La producción de electricidad en los Estados Unidos se genera  principalmente por la quema de combustibles fósiles tales como el carbón y el gas natural. Es relevante destacar que la demanda de electricidad ha ido  aumentando constantemente desde la década de 1980,  sin ningún signo de disminución. El aumento de la demanda de electricidad está siendo servida por la instalación de plantas de generación de electricidad a partir de combustibles fósiles. Puesto que los combustibles fósiles producen emisiones de dióxido de carbono dañinas, sería preferible la producción de electricidad a partir de fuentes de energía renovable como la energía por medio de viento y la energía solar, para mejorar el despliegue de la producción de electricidad. En la reciente conferencia de Doha,  en mayo de 2011, el Panel Intergubernamental de las Naciones Unidas sobre el Cambio Climático publicó un informe que establece lo siguiente: " Es probable que la energía renovable tendrá un papel mucho mayor en el sistema energético global en el futuro que hoy"

Las fuentes de  energía renovables  se consideran las opciones más prometedoras en un futuro próximo. De acuerdo con el Departamento de Energía de los  Estados Unidos, las granjas de energía por medio de viento en alta mar, podrán producir por sí solas  900 giga vatios de potencia lo que es suficiente para abastecer las necesidades de todos los Estados Unidos. De acuerdo con la Asociación Europea de la Industria Fotovoltaica, la energía solar que llega a la tierra, convertida en electricidad mediante granjas de  energía solar, podrían satisfacer las necesidades de energía global  10.000 veces más. Otras fuentes de energía renovables son  la energía por onda, la energía geotérmica,  etc. En los primeros seis meses de 2010, el 11 % de la electricidad en los EE.UU. fue producida por  fuentes de energía renovables. En marzo de 2011, China dio a conocer su nuevo plan de cinco años con un  objetivo de 11,4 por ciento de la energía generada a partir de combustibles no fósiles. El IGBT es una tecnología indispensablemente  necesaria   para el despliegue de todas las fuentes de energía renovables.
