Power Module

WARNING: This page is about a different car, the 2011 Nissan Leaf. However, it is still accessible from the selected car via links, so may be relevant.

The power module is composed of 6 power semiconductor IGBT (Insulated Gate Bipolar Transistor).
An IGBT is a semiconductor switch that is capable of switching ON/OFF at high speed.
An IGBT uses the IGBT drive signal from the driver to perform switching, converting the Li-ion battery DC power to AC power and supplying AC power to the traction motor.
