Abstract

This paper presents a single power-conversion AC-DC converter with noncomplementary active-clamp circuit that can achieve high power conversion efficiency. We adopted the active-clamp circuit with noncomplementary modulation strategy to suppress a voltage spike of the main switch and minimize the power losses caused by high turn-off switching current and circulating current. To achieve 1-kW power capacity, we used a series resonant circuit which provides zero-current switching turn-off of the output diodes. Moreover, it has a benefit of bidirectional core excitation, thereby that this circuit transfers the energy in resonant and linear way during a single switching period. The proposed converter is analyzed theoretically and verified experimentally using 1-kW prototype.
