This paper presents analysis in detail and designs a Zero-Current-Switched Quasi-Resonant SEPIC converter in full-wave mode. And based on the Power System Simulation Blocksets (SimPowerSystems) of Matlab6.5, it constitutes a simulation model of this SEPIC converter making use of the advantages of the blocksets in simulating non-linear、rigid and uncontinuous systems and being fitted for simulating circuits which contain switch devices. Through simulating integrating Matlab/Simulink software, simulation results confirm that this converter performs in zero-current soft switching and its performance is improved which is the same as the analysis results.
