[Amps] Source wanted for HV switch-mode power supply

[Paul Decker]

Hi Tomm , 



Actually, it is funny you say that.   I wanted to redraw the schematic into my schematic program so it could do autoroute and pcb layout.  When I did, I found that my pcb layout was limited to 100 pads, which forced me to break the schematic up into individual boards, so that work is already done ;)   The original pwm module is about 1"x1", it goes to a signal amplifier board, which goes to the h-bridge.  My H-Bridge board is a bit weird on the layout because I used some leftover heat sinks and kept the leftover parts placement.    After the HV transformer there is the HV  rectifier board.     Tim's original design doesn't provide any feedback but that could easily be added and the little pwm module be replaced to allow for a feedback control of some type.    For me, the HV transformer was the hardest part and I'm still not convinced I like what I have implemented, it may get some changes. 



As far as a kit, who knows, but I'll try to put design files up on my web page this weekend and if people want them, they can pull them from there.  



73 for now,

Once you get it working, it would be straight forward to lay out a few 
PC boards so others could do what amounts to a kit build.
