1. A power converter comprisingan input coupleable to a source of DC potential, an output coupleable to a load, an active reset switching network comprising first switch means coupled to said input, a series network coupled to said first switch means comprising second switch means operable substantially in anti-synchronization to said first switch means, a first capacitor coupled in series to said second switch means, a first inductor coupled to said first switch means and said series network, a second inductor coupled to said active reset switching network, third switch means coupled to said first inductor and said output and operable substantially in synchronization with said second switch means, whereby said first inductor provides energy to drive a zero voltage turn on transition for said first switch means.
