4 FAQs about Which generation of IGBT is used in solar inverters

What is IGBT in solar inverters?

IGBT (Insulated Gate Bipolar Transistor) is an electronic switch that performs the key functions to convert direct current from the solar cells to an alternating current in solar inverters. In the solar energy sector, when discussing inverters with many technical folks, the topic of IGBT is almost inevitable.

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) ofer 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.

What is a 4th IGBT?

The fourth IGBT is a trench-gate IGBT optimized to deliver low con-duction and switching losses for high-frequency switching such as in solar inverter applications. An IGBT is basically a bipolar junction transistor (BJT) with a metal oxide semiconductor gate structure.

Which IGBT has the lowest vceon?

As can be seen in the table, a standard-speed IGBT has the lowest VCEON, but the slowest fall time compared to the other two fast and ultrafast planar IGBTs. The fourth IGBT is a trench-gate IGBT optimized to deliver low con-duction and switching losses for high-frequency switching such as in solar inverter applications.
