  • Self-synchronized synchronous rectifier
    Patent number: 6707650
    Abstract: A power MOSFET gate protection circuit includes a limiter having a low voltage conduction threshold controlled by its own wiring and including a first portion connected in parallel with a divider and adapted to be connected to the gate of an associated power MOSFET and a second portion adapted to be connected to the source of the associated power MOSFET.
    Type: Grant
    Filed: May 10, 2002
    Date of Patent: March 16, 2004
    Assignee: Alcatel

  • Self-regulated synchronous rectifier
    Patent number: 6292380
    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.
