Abstract:
The impact of forward-recovery losses on Si IGBTs and diodes in the active neutral point clamped (ANPC) topology are analyzed with respect to two different pulse-width modulation (PWM) schemes. The analysis includes, in addition to [1, 2], detailed losses, maximum virtual junction temperatures Tvj,max and lifetime of the respective chips under typical operating conditions in solar applications. We demonstrate that forward-recovery losses mainly affect devices that do not limit system performance.
