All this sounds very interesting, unfortunately I'm not quite at a level to understand it all. But curiosity prompts me to ask this silly question: What difference does the feeding of two 50Hz sine waves into the mosfet gate drivers make instead of 50hz square wave & 20KHz SPWM? I recall you mention that mosfets do not like being turned on slowly - or am I misunderstanding something here ? Klaus
