| 摘 要： | 为了减轻航天器太阳能电池阵-蓄电池组电源系统的体积和重量,介绍了一种半桥式双向DC/DC变换器。对该变换器的工作原理进行了详细分析,并设计了双向半桥变换器在不同工作模式下的反馈控制环路。最后研制了一台600 W的实验样机,实验结果表明,该变换器不仅能够实现能量的双向流动,而且可以有效地减轻电源系统的体积和重量。

| Abstract: | In order to reduce the size and weight of solar array-batteries power supply system,a half bridge bi-directional DC/DC converter is introduced.The working principle of the converter is analyzed,and the feedback control loops in different working models are designed.A bi-directional DC/DC converter of 600 W is achieved.The experimental result shows that the converter can not only realize the bi-directional power flow,but also reduce the size and weight of the power system effectively. |
