9th January 2020, 15:43Of course this is “possible”; ANYTHING is possible. But this is not trivial. Basically, you need to chop your 200 VDC into pulsed DC, and step it up...5 replies | 524 view(s)

8th January 2020, 16:27I'm not going to analyze your entire circuit, but consider this: the resistors will have an instantaneous power of 360W. 30mS only provides half the...4 replies | 410 view(s)
