Hi,
in my circuit there are the two diodes to clamp the inductive kick back and recycle it to the filter cap. Did you have the diodes in place and s...

Hi,
The half bridge was mounted on a perf board, but the MOSFETS were connected through wiered several inches long.

Well this is bad but the circuit should work anyway. Make the wiring as short as possible. You do have the diodes in place right? Do you have a scope?

Hello,
I have a scope. What do you mean by bad? Are there any obvious faults?
Thanks for your help,
Paul
PS Do you really use that...

I meant the long connections are bad. Yes I do use the scope often. Can you post a picture of the gate waveforms?

Did you check that you mirrored the design properly?
when you're sure you laid out the circuit properly on paper, that's the next thing to check.

From the photos it looks like one or more of the zeners might be electrically touching one of the drain pin's via some excess solder. Although I can't...
