Driving IGBTs with unipolar gate voltage
Introduction
Infineon recommends the use of negative gate voltage to safely turn-off
and block IGBT modules. In areas with nominal currents less than
100tA the negative gate voltage is often omitted for cost reasons. The
following paper describes special considerations for a unipolar drive of
IGBT modules.

Turn-off to 0 V
The latest Infineon IGBT chip generations have several advantages.
Some highlights especially are a wider dynamic range, faster switching,
less switching losses and lower conduction losses.
When switc
