Abstract
This paper demonstrates the dynamic behaviors of paralleled high power IGBTs using trench and fieldstop technologies. Four
IGBTs are paralleled and standard deviation is adopted to represent the imbalance. Experiments are conducted under three different
operation conditions and at different temperatures ranging from -25°C to 125°C. The experimental results show that operation at
very low and very high temperatures usually aggravates the switching behaviors. There is a trade-off between the balance and the
losses at low temperatures. These results can help in the design of heat sinks in paralleling applications confronting very low
temperatures.
