  • Direct energy transfer converter
    Patent number: 7038922
    Abstract: The invention concerns a direct energy-transfer converter of the AC/AC or DC/DC type, including a self-regulated synchronous rectifier, in which the rectifier switches are controlled through one or more transformer windings. The converter includes a primary stage with at least one primary winding of a transformer and at least one controlled switch, with a secondary stage having at least one secondary winding (10) of the transformer, and a synchronous rectifier (1) with at least a first switch (20) which is self-regulated and conducting during the conducting phase of the controlled switch of the primary stage, known as the direct energy-transfer stage, and at least one secondary switch (30) which is self-regulated and conducting during the non-conducting phase of the controlled switch of the primary stage, known as the freewheel phase, and an output filter (5).

  • 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.
