| 摘 要： | 针对典型的半桥式双向DC/DC变换器拓扑结构特点,利用DCM模式下电感电流反向的特征,采用一种不额外添加半导体器件的软开关技术,减小开关损耗;采用多重化拓扑结构弥补DCM模式下电压、电流纹波大的缺陷;在控制方式上采用电压电流双闭环形式,将共用电压环的输出作为每个基本单元的给定电流,解决了并联结构的均流问题。

| Abstract: | For the characteristics of the typical half-bridge bidirectional DC/DC converter topology and the reverse inductor current in DCM operation,this paper adopts a soft-switching technology without increasing extra semiconductor devices to decrease turn-off loss.The DCM associated voltage and current ripples can be alleviated by multiphase interleaved operation.This paper adopts a voltage and current double close-loop control strategy to balances the inductor currents among cell modules using a same reference c... |
