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.
