Working Principle

The CM400DU-12H IGBT module is an advanced switching technology which uses insulated gate bipolar transistors (IGBTs) for power switching. IGBTs are basically three-terminal semiconductor devices which combine the benefits of MOSFETs and BJTs, providing high input impedance, low voltage losses and low EMI noise. This makes them very suitable for high-power switching applications.

The basic operation of an IGBT module is as follows: when a voltage is applied to the gate, a voltage difference is created between the emitter and collector, which increases current flow between them. This current can be controlled by adjusting the gate voltage and hence the current flow can be controlled precisely. This makes it suitable for applications where precise power control is needed.
