This paper presents a current-fed full-bridge boost dc/ac/dc converter with transformer isolation operating without switching power dissipation. The output voltage is regulated by dc/ac converter control frequency changes with a constant turn-off time of transistors. The proposed converter is devoid of parasitic oscillations, as all of the parasitic capacitances and inductances are included in a resonant tank circuit. In this paper, the system operation is first explained, then a mathematical description that is useful for its design is provided, and finally, a report on the implementation of a laboratory prototype with 1.4-kW power is presented.
