摘　　要：针对传统的桥式四象限变流器直流侧工作电压要求较高的缺点,提出一种准降压式新型四象限变流器拓扑,其直流侧工作电压下限值比桥式拓扑降低近一半,适用于直流电压较低的应用场合。该文运用状态空间平均法对这种新型拓扑进行建模和稳态理论分析。Matlab数字仿真与样机实验结果证实了该拓扑、模型及理论分析的正确性。In view of the drawback of traditional bridge 4-quadrant converters which need higher dc-side operating voltage, a new type quasi-buck topology of converters is proposed whose dc-side voltage is reduced by approaching 50%, thus appropriate for lower voltage applications. This paper presents the modeling with the state space averaging method, and steady state theoretical analyses of the converter. The validity of the topology and its model along with the theory is confirmed by both Matlab numerical simulations and experimental results.
