This paper introduced a design method of quasi-resonance forward converter with zero current switching（ ZCS） characteristic. In the circuit power switch can be cut off by using some resonant components,which can pick up operation frequency of the circuit,and obtain a high power density. The topology of the circuit was described in detail,and the operation principle was analyzed in the same way. The selection of the circuit components and the parameters design were illuminated. It is useful for supporting a design guide to those similar converters.
