Abstract
- This paper presents a single-switch single power-conversion (S^\text3 PC) power factor correction (PFC) converter. Using the series-resonant circuit, the S ^\text3PC converter provides bidirectional core excitation for the transformer and obtains higher power capability compared with the conventional single-switch PFC converters. Also, the series-resonant circuit provides zero-current switching turn-off for the output diodes, so that the reverse-recovery loss is alleviated. The regenerative snubber not only avoids the voltage spike of the switch but also recycles the absorbed energy. Because these features are obtained with only a single switch and through single power-conversion, the S^\text3PC converter has high efficiency and simple structure. The control algorithm derived from feedback linearization enables the S^\text3PC converter to obtain good controllability. Also, by using this control algorithm, the proposed converter performs both PFC control and output power control through single power-conversion. With these advantages, the S ^\text3PC converter provides maximum efficiency of 96.4% and high power factor in excess of 0.994. The proposed converter is theoretically analyzed in detail, and experimental results are applied to a 1-kW prototype to show its validity. [ABSTRACT FROM PUBLISHER]
