IGBT high power module (IHM)

IGBT High-Power Modules (IHM) are compact modules made of power semiconductors that are used as high-power switches in inverters, power electronics, and energy and HVDC technology.

IHM modules are extremely robust and are characterized by high reliability. Their temperature range is between -50 °C and 150 °C. They are available in two performance classes: IGBT High Voltage (IHV) and IGBT Low Voltage (ILV).

The modules of both power classes - ILV and IHV - are available as half- bridge, single- switch, chopper and diode modules. They differ in voltage and current ratings and package isolation. While the ILV module has a package isolation of up to 6 kV, the isolation strength of the IHV module is 10.4 kV. The ILV module can be used in the 1.2 kV and 3.3 kV voltage range, while the IHV module can be used up to 6.5 kV and switch currents up to 3.6 kA.
