摘　　要：针对倍流整流电路在应用中由于两电感寄生电阻参数不一致导致的电感电流不对称问题,采用PSIM软件搭建带倍流整流电路的全桥拓扑进行仿真。仿真结果显示:与两电感参数完全相同时的电流相比,两电感具有相同电感值但寄生电阻值不同时的电流不再具有相同的直流分量,通过仿真结果验证了理论分析的正确性,为更好的应用该电路提供理论依据。In this paper, the asymmetrical current between the two inductor is analyzed in current-doubler rectifier,which is caused by different parasitical resistors of the two inductor. PSIM software is used to build the full bridge topology with doubler rectifier circuit for simulation. The simulation results show that compared with the current of two inductor parameters, the two inductor has the same inductance value but the current of the parasitic resistance is no longer with the same DC component. And the correctness of the theoretical analysis is verified by the simulation results.It provides a theoretical basis for the better application of the circuit.
