Hi all,

I have this circuit that I am hope to use for HV electrolysis. It has
damaged every Mosfet and IGBT I have tried. It even damaged an IGBT
that is rated 600V and 58 amps. The circuit works without a hitch when
the load is resistive like a light bulb.

But as soon as I hook up a transformer the IGBT fails in 10 seconds. It
has trouble with inductive loads.

I have tried clamping the IGBT with a diode to no avail.

Please, somebody take a look and tell me what I am doing wrong. My
power source is and auto inverter.

I can see it here, but a lot of news servers do not allow pictures on groups without "binary" in the name. Thus most people won't see the picture, or may not even see the post.
