Are insulated-gate bipolar transistors a good choice for solar inverter applications?

For solar inverter applications, it is well known that insulated-gate bipolar transistors (IGBTs) offer benefits compared to other types of power devices, like high-current-carrying capability, gate control using voltage instead of current and the ability to match the co-pack diode with the IGBT.

Which EF-ficiency is possible for a solar inverter design?

The latest 600-V trench IGBT is optimized for switch-ing at 20 kHz. It can be seen that this IGBT has lower total power dissipation compared to the previous-generation planar IGBT (Fig. 4). We can conclude that the highest ef-ficiency possible for a solar inverter design, a trench-gate

Which IGBT has the lowest power dissipation?

Ultrafast IGBTs switching at 20 kHz provide the lowest power-dissipation levels compared to fast and standard-speed devices. And of the two ultrafast types shown on the right, a trench-gate IGBT dissipates the least amount of power. IGBT, is the device of choice for the high-side IGBTs. The same question arises for the low-side IGBTs.

Can a co-pack diode be optimized for a low-side IGBT?

Co-pack diodes across the low-side IGBTs can be optimized to minimize losses during freewheeling and reverse recovery. Let’s assume a 1.5-kW solar inverter is being designed with a 230-Vac output. Which IGBT shown in the table will give the lowest power dissipation at 20 kHz?
