Abstract
A self-regulated synchronous rectifier is connected between a secondary transformer winding and an LC filter. The rectifier includes two MOSFETs each having a gate connected in series with a gate protection circuit. Each gate protection circuit includes a divider bridge and a switch connected in parallel with the divider bridge and having an open position and a closed position and the rectifier includes a control device for controlling the switches which receives an input signal proportional to the input voltage of the rectifier and produces output signals for controlling the switches.
