Abstract
A simplified time domain gain curve of LLC resonant converter for wide range input application was proposed.The converter was divided into two kind of modality during one switching cycle and the simplified gain curve of the converter was derived by establishing the time domain state equation together with initial condition and boundary condition.A design method of LLC resonant converter for wide range input was proposed,considering the quality factor Q and inductance ratio h as key factors.Finally,a 200W prototype was build.The prototype can realize power conversion with high efficiency from 120 V to 220 V input voltage range,which verifies the feasibility of the proposed method.关键词
