Design of Soft Switching Sepic Converter Fed DC Drive Applications
High efficiency DC-DC converters with high-voltage gain have been researched due to increasing demands. A soft-switching single-ended primary inductor converter (SEPIC) is presented in this work. An auxiliary switch and a clamp capacitor are presented in this project. A coupled inductor and an auxiliary inductor are utilized to obtain ripple-free input current and achieve zero voltage-switching...
متن کاملImplementation of SEPIC/Zeta Three-Port Bidirectional DC-DC Converter for Renewable Energy Applications
In this paper an efficient topology of (Single Ended Primary Inductor Converter) SEPIC/Zeta converter is proposed to interface renewable energy sources and the load. The proposed converter is obtained by the integration of the bidirectional converter and the full-bridge converter. As the output voltage of the proposed converter is not reversed this topology provides remarkable advantages than t...
متن کاملHigh voltage gain DC-DC resonant converter
In this paper, a DC-DC resonant converter with high voltage gain and small size is studied. To reduce the size and weight of this converter, the operating frequency should be as high as possible. In this research, the frequency changes from 120 to 200 kHz. Due to the high operating frequency, it is necessary to reduce the switching losses using soft switching methods. Resonant converters are su...

متن کاملNew topologies for Transformerless Single-Stage AC/DC Converter
This paper presents a high step-down tranformerless single-stage single-switch ac/dc converter suitable for universal line applications (90–270 Vrms ). The topology integrates a buck-type power-factor correction (PFC) cell with a buck–boost dc/dc cell and part of the input power is coupled to the output directly after the first power processing. With this direct power transfer feature and shari...
