Dear Experts,
I want to make +/-21V output for an LLC PSU. I built the prototype but it seems that the bridge rectifier does not work. I can se only a little signal across VD-VS pins. It looks like the MOSFETs body diodes work only. I see it also on the thermal camera that it gets too hot, so the Rds on does not bridge out the body diode.
Here is a sketch of the actual circuit - actually I completed it with 15V Zener-diodes between pins VDD and VS to avoid overvoltage, together this I increased the 10R series resistors to 1kR:
