| 摘 要： | 提出了一种应用于低功率场合的双向DC/DC变换器。该变换器采用初、次级隔离的形式,其初级为隔离型Boost电路,次级采用半桥倍压电路。变换器的输出端为直流母线,能量反向流动给蓄电池充电。当直流母线故障时,蓄电池通过升压来维持母线电压。实验结果表明,在相同功率器件的条件下,该变换器可以实现能量的双向流动,适用于蓄电池等功率变换系统。

| Abstract: | This paper presents a bidirectional DC/DC converter applicable to low power applications.The proposed topology is based on an isolated Boost on the primary and a half-bridge on the secondary side of a high frequency isolation transformer.The proposed converter can achieve bidirectional flow of power using the same power components,and it is specially attractive for use in battery charge and discharge,UPS etc.The output of the proposed converter is the DC mains,and power of the DC mains can charge to battery.On failure of the DC mains,the converter serves as a Boost circuit to keep DC mains.Experimental results prove that this converter can realize bidirectional flow of power and it is specially attractive for use in battery system. |
