    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.

    Abstract: The converter has a transformer with primary and secondary windings. A rectifier has one auto-controlled interrupter (20) passing during conducting phase of a controlled interrupter. Another auto-controlled interrupter (30) passes during non-conducting phase of the controlled interrupter. A MOSFET control unit passes the interrupter (30) independently of voltage to boundary of the secondary winding during free wheel phase.

    Abstract: The metal oxide semiconductor field effect transistor (MOSFET) has gate (12) connected in series with gate protectors (28,29). The gate protectors have dividers (13,16) and a switches (17,18) connected in parallel with divider. A controller (19) receives input signal (20) proportional to input voltage of rectifier and outputs signals (21,22) for controlling switches.

    Abstract: The MOSFETs having low voltage conduction thresholds, are controlled by their gate-source wirings. The transistors have sources parallel to voltage dividers, and gates that are adapted to be respectively connected to gates and source of associated power MOSFETs. An independent claim is included for self-synchronized rectifier.
