Power module

From Wikipedia, the free encyclopedia

High power IGBTs (here a 3300V, 1200A switch) are obtained by connecting tens of dice in parallel in a power module.

A power electronic module provides the physical containment for several power components, usually Power semiconductor devices. This package provides an easy way to cool the devices and to connect them to the outer circuit.

Classical example of structures availables as power modules are:

  • switch (MOSFET, IGBT), with antiparallel Diode;
  • half bridge (inverter leg, with two switches and their corresponding diodes)
  • three-phases inverter (six switches and the corresponding diodes)
