Abstract :
In traction applications, power electronic converters experience wide variation in DC link voltage during operation. The purpose of this paper is to study the variations in turn-on and turn-off switching energy losses in the IGBTs with the DC link voltage. The IGBT switching characteristics are measured at various operating conditions, and turn-on and turn-off switching energy losses are determined. The experimental data are used to deduce a simple mathematical relationship between the switching energy losses and the DC link voltage. The results are useful for precise evaluation of IGBT switching energy loss over a wide range of operating conditions.
