Abstract

A high-performance plasma-display-panel ´sustain´ power supply is proposed. The proposed convertor consists of a boost convertor for power-factor correction (PFC) and a half-bridge flyback convertor for DC-DC power conversion. The boost convertor reduces the reverse-recovery loss of the diode by adding a simple inductor-diode branch. The half-bridge flyback convertor is driven in complementary control for zero-voltage switching and also its output diode commutates with zero-current switching. The proposed convertor is analysed and optimised for high power efficiency. Experimental results for a 300 W convertor at a constant switching frequency of 100 kHz are obtained to show good performance of the proposed convertor.
