Three-Phase Inverters and Short-Duration Overvoltages

The goal of this initial testing was to develop and demonstrate a laboratory test procedure suitable for evaluating the contribution of three phase inverters to short-duration overvoltage events. This report
Lecture 23: Three-Phase Inverters

One might think that to realize a balanced 3-phase inverter could require as many as twelve devices to synthesize the desired output patterns. However, most 3-phase loads are connected in wye or delta,
