摘　　要：分析了电网不平衡条件下三相PWM整流器主电路并进行建模。在此基础上分析了交流侧电感的设计,探讨了在电网平衡与不平衡两种状态交替变更的条件下交流侧电感的设计方法。如果三相PWM整流器采用不平衡控制策略,那么电感的设计应充分考虑在电网平衡条件下PWM整流器的性能和控制效果。通过仿真验证这种方法的可行性和实用性。The main circuit of three-phase PWM rectifier under unbalanced input voltage conditions was analyzed and then the mathematical model was constructed. The AC-side inductor design method was analyzed based on it,the design method of AC-side inductor was discussed under the conditions of alternating change balance and imbalance input voltage. If the three-phase PWM rectifier using unbalanced control strategy, then the inductor design should be take full account of the performance and control effect of the PWM rectifier under the balanced volt- age conditions. Simulation results show the feasibility and practicality of this method.
