초록

This paper proposes a new high efficiency single-phase AC-DC boost converter for power factor correction. Lossless commutation circuit is interposed in the proposed converter for soft-switching. Due to this commutation circuit, the converter operates in 9 mode. In spite of changing input voltage and load, It attracts a constant DC output voltage because of the PWM control scheme using both the output voltage feedback and the input voltage feedforward. The converter is suitable for high power applications and operates in continuous conduction mode. In this paper, a 2.4[kW] converter is designed and simulated.
