Electrical Engineering College, Southwest Jiaotong University, Chengdu 610031, China) Abstract: Owing to possessing the merits of low harmonic current component fed to the catenary, high power factor, bi directional flow of energy, excellent dynamic response and so on, fourquadrant converter (4QC) is applied to AC drive electric locomotive and electric multipleunit as lineside rectifier. T he inductance valuefor 4QC is vital to the performance of the PWM rectifier. Transient process of AC side current tracing and vector relation of AC loop are analyzed. According to meeting thetracing performance of transient current and limit of the maximal modulation ratio, a scheme is put forward to design AC side inductance of for 4QC for AC drive locomotive. Meanwhile, the effect of catenary voltage fluctuation on inductance design is analyzed in the pa per. The results of simulation verify the feasibility and correctness of the proposed method. Key ords: fourquadrant converter; PWM ; design of inductance; AC drive
