摘要
在实际应用时,四象限变流器可能存在变压器漏抗大的情况。探讨了变压器漏抗对四象限变流器控制的影响并以瞬态电流法为基础,通过引入补偿环节,弥补变压器漏抗大对变流器控制带来的不良后果。仿真结果表明,通过调整补偿系数来改善四象限变流器控制性能是行之有效的方法。
In the actual application, large transformer impendence exists in four quadrant converter.The influence of control of the transformer impendence over four quadrant converter is discussed. Based on the method of transient current, the compensating modulus is inducted to ameliorate the effect of large transformer impendence on converter control. The simulation results show that regulating compensating modulus can improve the performance of four quadrant converter effectively.
