I have never designed an inverter and all the ones I find online do not simulate so I can't check my results and test the circuit for outputting a clean enough signal.
Unfortunately I already looked at that option and ruled it out because I would need to draw power from this power supply in order to power the drive IC. I only have the HV line to work with. I am sorry for forgetting to mention that in the description of my problem.
I am designing a HV (450 to 950 VDC) to LV (24 VDC) converter. I am having problems creating the controls for the switching transistor and choosing the transistor. The schematic is a standard buck converter with S being the transistor and sensing from just before the inductor. I would also...
