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.

IGBTs and Solar Inverters

IGBTs are excellent choices for use in solar inverters where voltage from a solar panel array on a residential or commercial building is converted from direct current to alternating current at a specific voltage output and frequency. IGBTs, like MOSFETS, use voltage rather than current as a means of control, with current applied across their gates being typically very low.

IGBTs are a type of bipolar junction transistor or BJT which have a semiconductor gate structure composed of metal oxide. BJTs have a higher current capability compared to MOSFETs. The speed at which an IGBT turns off is determined by how rapid the minority carrier recombines. The turn off time has an inverse relationship with the voltage drop or VCEON. This means that IGBTs with inherently rapid turn off times have a higher voltage drop and vice versa. Ultra fast IGBTs do switch off much faster than standard IGBTs, even if the IGBTs have the same dimensions and are basically manufactured the same way. The exact combination of speed and voltage drop is determined by adjusting the minority carrier recombination rate this in turn controls the turn off time.

Four switches are typically employed in a solar inverter. Two of the switches are high side IGBTs, while the other two are low side IGBTs. Solar inverters of this type produce a sinusoidal wave form and single phase alternating current. The frequency and voltage depend on the specific use required. In a household solar array system, the inverter will normally deliver voltage and frequency similar or the same as that provided by the mains electricity provider as it will be used to power household appliances that are designed to use mains power.

Inverters for installation in a residential capacity are usually linked to the power grid. These installations usually provide power to the grid when there is a surplus with tariff benefits depending on the location and provider. To enable this feature, the solar inverter is required to pulse width modulate the IGBTs above 20kHZ. The modulation frequency is normally around 50 to 60 Hz. This sort of pulse width modulation means that the two outut indicators can be maintained relatively small in size and they will also have the benefit of suppressing harmonics effectively.

This sort of solar inverter has switching speeds much higher than can be heard by the human ear so they remain basically noiseless.

To keep the power dissipation as low as possible, pulse width modulation is restricted to the two high side IGBTs while the low side IGBTs are commutated at 50 to 60kHz.
