| 摘 要： | 针对采用同一组电池同时给多台不间断电源(Uninterrupted Power Supply,简称UPS)供电的应用,提出了一种没有环流的UPS电池模式拓扑;分析了该拓扑的两种工作模式,即Buck工作模式和Buck-Boost工作模式,指出它们互相独立,没有环流回路.此外,根据该拓扑的特点,提出了分时控制和同时控制两种控制方法;比较了它们的优缺点.最后研制了两台6 kVA的样机.实验结果证明了该拓扑及其控制方法的有效性.

| Abstract: | Based on the application that one team of batteries provided power source for several uninterrupted power supplies(UPS),a kind of UPS topology without circulation current is proposed.The topology has two operation circuit modes:Buck operation mode and Buck-Boost operation mode,and these two modes operated individually without circula-tion current loop.In addition,the virtues and drawbacks of two control methods,i.e simultaneous control and non-simulta-neous control,are compared.At last,two 6kVA UPS prototypes are produced and the experiment results verify the topology and its control methods are available. |
