Abstract
An off line resonant converter includes a boost storage inductance circuit coupled to a switcher circuit that includes stacked first and second passive switching devices coupled to the boost storage inductance circuit and stacked first and second active bidirectional switching devices coupled to the stacked first and second passive switching devices. The stacked first and second active bidirectional switching devices generate a square wave signal and alternately store energy in and receive energy from the boost storage inductance circuit such that a pulsating current is conducted between the boost storage inductance circuit and the switcher circuit. The pulsating current is bidirectional and flows in a direction responsive to a polarity of the ac input line voltage. A resonant circuit is coupled to an output of the switcher circuit to receive the square wave signal from the switcher circuit to generate an output of the resonant converter.
