摘　　要：分析了一种等效48脉波整流器的电路结构,即采用两重24脉波整流器来实现48脉波整流器。在理想情况下,对等效48脉波整流器的谐波消除情况进行了分析,运用Matlab进行了仿真试验。仿真和试验结果验证了理论分析的正确性和方案的可行性。Based on the 24-pulse rectifier,the circuit of an equivalent 48-pulse rectifier was analyzed.And the harmonic cancellation of the line side current under ideal conditions after adopting the equivalent 48-pulse rectifier was discussed.Matlab was used as the simulation tool,and the simulation results prove the correctness of the theory.The waveforms of the actual primary and secondary line currents were obtained.The results show the theory＇s correctness and availability.
