| 摘 要： | 对一种改进型Zeta变换器拓扑引入了三态开关电路,使得原有的拓扑在得到同降压型驱动电源一样的高动态性能的同时,也使系统获得了更好的稳定性,并降低了对元件参数的依赖程度。运用PSIM软件对系统闭环进行了仿真验证。

| Abstract: | This paper introduces a three-state switch circuit into a modified Zeta converter topology,so not only the modified topology obtains a high dynamic performance with the buck drive power,but also the system gets a better stability,and reduces the dependence of device parameters.The system closed loop was simulated and verified based on PSIM. |
