- Abstract
- A high-performance front-end rectifier system is proposed for telecommunication power supplies. The proposed system consists of a boost converter for power-factor correction (PFC) and a asymmetrical half-bridge zeta converter for DC-DC power conversion. A cost-effective implementation for a continuous-conduction-mode boost converter is proposed for a PFC circuit. With a simple passive approach, the proposed PFC circuit minimises switching losses by reducing the reverse-recovery current. The asymmetrical half-bridge zeta converter operates under zero-voltage switching for the power switches and its output diode commutates with zero-current switching. The proposed front-end rectifier system is analysed and its design considerations are discussed. Experimental results for a 300 W prototype at a constant switching frequency of 100 kHz are presented to verify the analysis and to show the performance of the proposed system.
