This paper presents an efficient power-factor correction (PFC) scheme for plasma display panels (PDPs) to reduce harmonic currents and power consumption. A high-efficiency interleaved boost converter is proposed, which can reduce the conduction losses and diode reverse-recovery problems in the continuous-conduction-mode operation. A zero-current switching (ZCS) condition is obtained to solve the reverse-recovery problems of the output diodes. In addition., a control strategy is suggested for the use of the proposed converter in a practical design. A high power factor can be achieved without sensing the input voltage. The analysis of the proposed converter and its design considerations are presented in detail. The experimental results based on a 600-W prototype are discussed to evaluate the proposed converter for a PFC circuit in a 50-in PDP power supply unit.
