Abstract

A considerable improvement in power semiconductor device utilisation seems possible if the output current of power stages is actively limited by thermal feedback from the power converter. To illustrate the potential utilisation benefit in main switching devices, the variation in usable current with operating conditions is examined for several devices used in a constant frequency PWM VVVF inverter, and operated under conditions to keep their junction temperature constant
