1. A method of damping unwanted ringing in self-driven synchronous rectifiers including first and second self-driven synchronous devices each having respective activation terminals, comprising:

  • (a) activating a first switching device to dampen any unwanted ringing on said activation terminal of said second self-driven synchronous device at a first time when said first self-driven synchronous device is active and said second self-driven synchronous device is inactive; and

    (b) activating said second self-driven synchronous device at a second time when said first self-driven synchronous device is inactive.
