摘要
在降压变换器、升压变换器和具有升降压功能变换器的基础上,研究了一种简单、高效、宽输入输出电压范围的DC-DC升降压电路拓扑,可以根据输入输出的大小关系来选择相应的工作模式,分为降压模式、升降压模式和升压模式3种。在控制过程中各模式之间能实现无间隔切换,并用实验验证了该拓扑的高效性。
Based on the buck converter, boost converter and the buck-boost converter, this paper introduces a kind of simple, high efficiency with wide input and output voltage step-down DC - DC converter, it can choose corresponding work mode according to the the input and output relationship, and it is divided into 3 kinds of step-down, buck-boost and step-up mode. In the process of control, the modes can realize no interval between switches, efficiency of the proposed topology is verified by an experiment.
