含耦合电感的交错高降压比DC-DC变换器
Interleaved High Step-down Ratio DC-DC Converter with Coupling Inductor
摘要
Abstract
To solve the problems of low step-down ratio and high voltage stress of power devices in traditional Buck circuit,a new inter-leaved Buck circuit based on coupled inductor is proposed.By selecting the appropriate turns ratio of the coupling inductor,the converter can prolong the duty cycle and achieve a low conversion ratio.Interleaving technology and element rearrangement technology are used to reduce the voltage stress of power devices.In addition,compared with the traditional Buck circuit,the proposed converter has higher effi-ciency.The working principle of the proposed converter is discussed and the performance is verified by simulation and experiment.关键词
