摘要
为了实现复合电源中超级电容器与蓄电池的有机匹配,改善蓄电池的性能和延长其使用寿命,本文提出了一种新型的具有升降压功能的双向DC/DC变换器,使复合电源系统在对外充放电过程中,超级电容器与蓄电池的功率按电池"最佳"工作状态进行分配。通过分析论证和实际电路测试,双向DC/DC变换器能够满足超级电容器与蓄电池的良好匹配,实现了复合电源系统的稳定工作。
In order to matched the ultra capacitor and battery in compound power supply, and improved the performance and prolong use life of battery. A new bidirectional DC/DC converter was put forward in this paper, which have step up and down function. In the process of charge and discharge, the power of ultra capacitor and battery distribute according to the best work state of battery. Bidirectional DC/DC converter could be capable of meet the matching of ultra capacitor and battery by analysis and practice test, ...
