2Kw AC-DC psu

Building a 200V 2Kw Battery charger.

i am building a 2Kw battery charger for an EV conversion. stage one is pfc (Power Factor Correction). i had it working for a little while until it blew, had the wrong code on the controller, wasn't monitoring anything, i have no clue why it blew. plan to re code from the beginning.

i have tested a buck converter at 1kw, will be building a new one to add as stage two, rated for 2kw.

FPAB20BH60B - Ti - all in one power stage.
random discrete components.
atmega8 - avr - the controller

KCF25A40F - High Power Diodes
ACS712 - Current sensor

Enjoy this project?

Hi Robert, yes I'm interested in that project. In my garage I have some old radio transmitter tubes that I always kept "because I woud want to use them some day". I was looking for a way to reduce the size of the power supply, and you seemed on the right track.

That sounds like a fun future project!  I'm almost done with the design of the full AC-to-2kV chain, so I've started a new project for the #250W 2kV Power Supply.  I expect to have the preliminary circuit and board layout finished soon.

Interesting project. Would it be easy to modify to a 2kV 200Watt supply?

not this design, but a 200w PSu isn't that hard to build.  if you not worried about power factor, a Flyback converter is fairly simple to get working. with 2KV you are going to want a fast switching speed, however have a look here for a guide to building a flyback PSU

I realize this may be a little late, but my current project actually includes a 1.95kV supply.  It's intended to provide a > 5kW output but is easy to scale down to your 200W range.
