Abstract

A transformer-based power conversion system includes a primary coil is provided in a current path that includes a single energy switch. An oscillator is coupled to a control input of the energy switch. The design conserves switch-based losses as compared to prior designs because a single switch is provided in a current path occupied by the primary coil. The design also provides improved conversion efficiency because parasitic capacitances associated with the energy switch cooperate with charge transfers generated by the oscillator.
