摘　　要：文章应用能量守恒原理,通过对牵引逆变器交流侧瞬时功率的计算,推导出牵引逆变器在方波工况下的直流输入电流谐波。以此为基础,可进行直流侧电路的谐波计算。最后用Matlab/Simulink对直流电网供电的牵引逆变器进行仿真,验证了理论分析的正确性。Calculations of harmonics of DC input current of the traction inverter operating at square wave mode are deduced in this paper based on AC side instantaneous power calculation of the inverter. Then computing harmonics of DC side current is conducted. A simulation using Matlab/Simulink for an traction inverter supplied by a DC voltage system is performed,and the theoretical analysis in this paper is verified by the simulation.
