To minimize these problems, a non-isolated bridgeless buck-boost single ended primary inductance converter (SEPIC) using coupled inductor is introduced at the front end of the SMPS, which is operated in discontinuous conduction mode (DCM). This proposed technique reduces the Total Harmonic Distortion...
Power Management Texas Instruments Incorporated Benefits of a coupled-inductor SEPIC converter By John Betten Applications Engineer The single-ended primary-inductor converter (SEPIC) is capable of operating from an input voltage that is greater or less than the regulated output voltage. Aside from ...

This article explains how to design a SEPIC converter with a coupled inductor. Basic operation Figure 1 shows a simple circuit diagram of a SEPIC con- verter, consisting of an input capacitor, CIN; an output capacitor, COUT; coupled inductors L1a and L1b; an AC coupling capacitor, CP; a ...
耦合电感时,必要且理想的匝数比是1:1,因为在输出电压纹波为一定水平的条件下,各绕组所需的电感仅为分立电感所需值的一半(见“参考文献”部分中Ćuk和Middlebrook的论文:“Coupled-Inductor and Other Extensions of a New Optimum Topology Switching DC-DC Converter”)。 电容耦合栅极驱动电路 栅极驱动电容Cblk1...

The SEPIC (Single-Ended Primary Inductance Converter) topology is used in application that require characteristics of both a buck and a boost regulator,
The DC-DC converter is now widely used in renewable energy conversion systems such as photovoltaic. They serve to adapt the input voltage of a system to the desired output voltage. The SEPIC converter (Single-Ended Primary Inductor Converter) is a converter that has several advantages over other...
Using a coupled inductor takes up less space on the PCB and tends to be lower cost than two separate inductors. The capacitor Cs isolates the input from the output and provides protection against a shorted load. Figure 2 and 3 show the SEPIC 3、 converter current flow and switching ...
