摘　　要：以零电压开关准谐振升压变换器(Boost ZVS-QRC)为例,论述了准谐振变换器的工作原理。应用推广的状态平均法原理建立了准谐振变换器的状态空间平均法模型,并通过MATLAB软件进行典型Boost ZVS-QRC的电路模型和数学模型仿真对比,结果表明合理利用状态空间平均法,同样适用于谐振变换器的建模。同时给出了处理复杂系统的MAT-LAB仿真方法。The operation principle of quasi-resonant converters are presented for example of zero-voltage-switching quasi-resonant boost converters . State space averaging models of Boost ZVS-QRCs were founded based on extend statespace averaging principle, the waveforms of simulations of typical ZVS-QRC boost converter circuit models and mathematic models were compared by MATLAB software. Simulation results show that the extend state-space averaging principle was applicable quasi-resonant converter modeling. Simulation method was presented for complicated system by MATLAB software.
