What is an IGBT-inverter?

An IGBT-inverter is an inverter build with IGBT power modules to ensure high voltage/power switching functions. The IGBT power module is considered the ‘heart’ of the electrified drive train. Similar to a human heart distributing energy throughout our bodies, the power module functions as a human heart in the electric drive train for EV/HEVs.

What is an IGBT power module?

An IGBT is a is power semiconductor die and is the short form of insulated-gate bipolar transistor. An IGBT power module is the assembly and physical packaging of several IGBT power semiconductor dies in one package. The dies are normally connected in a selected electrical configuration such as half-bridge, 3-level, dual, chopper, booster, etc.

What is an IGBT in a solar inverter?

IGBTs are also often found in solar inverters, where they perform the key function of converting DC from solar cells to the AC required by various electrical equipment. Regardless of their specific applications, IGBTs generally contribute to high efficiency and space-saving in the circuits.

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.
