Abstract :
This paper describes an AC-DC converter using a universal input voltage type three-phase power factor correction (PFC) circuit and phase-shifted zero voltage switching (ZVS) DC-DC converters. The AC-DC converter has features of low impressed voltage on the semiconductors, high frequency operation, and high efficiency, which are confirmed through experiments. Moreover, the PFC circuit is capable of controlling the voltages of two output capacitors connected in series, individually. The ZVS DC-DC converters, on the other hand, reduce the output voltage ripple at the switching transient with the phase-shifted control. The efficiency of the AC-DC converter is improved 1.3% higher than that of our conventional products.
