Single ended primary inductor converter(SEPIC) topological structure of the converter can achieve boost,and accomplish buck and high efficiency.The topological structure and the working principles that complete the transmission of the power are introduced,and then the design principles and the methods of which the coupled inductances cuts the input current ripple are emphatically discussed.On the basis of the principles,through designing a SEPIC circuit and the relevant control chip,the correctness of the analysis is proved.
