摘　　要：反激变换器在使用中存在多种寄生参数,极大地降低了其电路性能。从潜电路角度分析了带有寄生参数的反激变换器,研究了其工作模态及工作方式,并通过仿真进行理论验证。研究表明,反激变换器电路中的寄生参数会导致其潜电路模态数量增加,通过调控寄生参数可以降低潜电路的影响,使电路工作在正常模态。There are many parasitic parameters in flyback converter,which greatly reduces its circuit performance.The flyback converter with parasitic parameters is analyzed from the perspective of sneak circuits,and its working mode is studied and theoretically verified by simulation.The results show that the parasitic parameters in flyback converter will increase the number of the subcircuit modes,and the effect of sneak circuits can be reduced by modulating the parasitic parameters so that the circuits can operate in normal modes.
