Characteristics Analysis of a Forward Converter by Finite Element Method Considering Hysteresis and State Variables Equation

히스테리시스를 고려한 유한요소법과 회로 방정식을 이용한 포워드 컨버터의 동작특성 해석

This paper presents a method to analyze a forward converter. A transformer is coupled with the forward converter electric circuit and then the finite element analysis considering a hysteresis phenomenon of magnetic core is carried out when the primary or the reset winding conducts current. The analytical method is used to reduce the computation time when the reset winding circuit of the transformer turns off. As a result, the simulation results show a good agreement with experimental ones.
