N2 - In this paper, a single-stage AC/DC boost-zeta converter with soft switching operation is presented. To make power factor high, a boost PFC cell with discontinuous conduction mode (DCM) is presented. Two switch zeta DC-DC module with critical conduction mode (CRM) is introduced for galvanic isolation and soft-switching operation. In addition, the output diode turned off under zero-current-switching (ZCS) condition and its reverse-recovery problem is alleviated. Besides, voltage stresses of the main switches are clamped to dc-bus voltage by clamping diodes and the current in the leakage inductor is absorbed by clamping diodes into dc-bus capacitor and it is reprocessed by the two switch zeta DC-DC module. The operational principle and a steady-state analysis of the proposed converter are provided in detail. In order to verify the theoretical analysis, experimental results based on a 24[V]-60[W] prototype are presented.
