Abstract

A single-stage, isolated, LCC resonant based ac/dc converter incorporating power factor correction (PFC) and output voltage holdup is proposed. The operation of the resonant circuit enables a narrow switching frequency range and ZVS operation down to no-load. An LC output filter renders it suitable for low voltage, high current applications. The Rectifier Compensated Fundamental Mode Approximation (RCFMA) method is used to provide an accurate yet simple analysis of the circuit. Initial results from a 3.3 V, 30 A prototype are presented.
