Hi, I want to drive the mosfets in asymmetric half bridge topology. This is an application for 3 phase switched reluctance motor. Since the high and low side mosfets are on and off at the same time, I'm confused about how to give ground to bootstrap capacitance. Is there any application note or reference design about this issue? Or any recommendations please. Thanks.
Can you please help send me the schemetic? does the Page 27 of UCC21520 datasheet provide some useful information? if not, can you please advise what challenges you may have for your bootstrap design? Thanks.
At this moment, I assume Page 27 of UCC21520 datasheet provide some useful information, and think it is resolved. Please reopen by reply if you have any further questions.
