摘　　要：分析了已有文献提出的正反激均压拓扑中均衡过程存在振荡且均衡电流/速度受正反激变压器限制的问题,提出了纯正激均压拓扑,在原来的基础上只需增加少量的元件,且均压原理与多绕组变压器拓扑(MWTT)相同,所以保留了它的优点。最后通过仿真和实验初步验证了所提纯正激均压拓扑的有效性。The problem that the balancing process in the forward-flyback vohage balancing topology proposed in the existing literature has oscillation and the balancing current/speed is limited by the forward-flyback transformer is anaiyzed.A pure forward balancing voltage topology is proposed,where only a small number of devices are needed additionally,and which follows the same principle as multi-winding transformer topology(MWTY)to achieve voltage balancing,so its original advantages are preserved.Finally,the effectiveness of this pure forward voltage balancing scheme is preliminarily verified by simulation and experiment.
