Cascaded boost converters provide more voltage gain than single boost converters, but they are still unsuitable for high step-up voltage conversion due to gain and hard switching conditions. To improve the voltage, gain of the cascaded boost converter, a coupled inductor can be used but the leakage inductance causes a voltage. To overcome these problems, a high step-up converter is proposed in which a cascaded structure, coupled inductor, and a lossless passive snubber are utilized together. The proposed converter has zero current and zero voltage switching conditions at turn-on and off instants. First, the proposed converter is theoretically analyzed, and then its design and simulation in OrCAD software are presented. Furthermore, the experimental results of the prototype verify soft switching conditions and high step-up gain. Manuscript profile
