Hello All,

I am trying to simulate a full bridge converter with synchronous rectification (schematic.bmp). I would like to monitor the gate signals to the transistors, but the scope does not appear to pick up switch signals.

I found a not so elegant work around (see the mess circle red in schematic.jpg). I was wondering if there is some easier way.

The problem seem to be the output of the alpha control (see subcircuit.jpg).


Any suggestions would be greatly appreciated.
 

FYI: (e-mail from Powersim)
