- Abstract
- A bridgeless dual-boost rectifier with reduced diode reverse-recovery problems is proposed for power-factor correction (PFC). In the proposed rectifier, conduction losses are lowered by essentially eliminating the full-bridge diode rectifier. The body diodes of the power switches are utilised as output diodes. A coupled inductor is designed to reduce the reverse-recovery problems of the body diodes. Zero-current switching is realised when the body diodes are turned off. In addition, for the use of this topology in a practical design, a control strategy is suggested by employing the linear peak current mode (LPCM) control. The LPCM control is implemented on leading-edge modulation, providing an efficient control scheme to obtain a high power-factor. The proposed rectifier is investigated theoretically and its design considerations are provided in detail. Finally, the experimental results based on a 500 W prototype are discussed to evaluate the performance of the proposed rectifier for a PFC circuit.
