A DC-DC converter using two transformers is proposed. One transformer delivers the energy to a load when a switch is on and the other transfers the flyback energy to a load when a switch is off. The primary windings of the two transformers function as choke inductance alternately, and thus the output voltage control by means of the duty ratio and the zero-voltage-switching are possible without an additional inductor. The breadboarded prototypes of the single output and the two outputs have confirmed the principles of operation and demonstrated the high conversion efficiency.
