Using the STGW35HF60WD advanced PT IGBT in parallel

Introduction
When two or more IGBTs are connected in parallel to improve the total efficiency in high
output power systems, special care is required to ensure that current sharing between the
devices is as equal as possible. Current sharing is mainly influenced by differences in IGBT
static parameters, circuitry layout (both driving and power) and thermal imbalances. All of
these elements must be considered, especially when PT (punch-through) IGBTs work in
parallel, due to their
