I wonder that, should we use separate isolated power supplies for each of the high side elements in a 3 phase bridge configuration and one for low sides? I used one common supply for all igbts' gate but i faced some problems. I rearranged the ground path, and it seems that problem has gone, at least at low voltage dcbus. I'll try at high voltage dc bus but which one should i use? I mean, using separate supply is a must or only better than other way? and can a proper common supply circuit do the job without problem?
