Design of PWM Triggered SEPIC Converter Using Zero-Voltage Zero-Current Switching

This paper presents the design, simulation and fabrication of single-ended primary-inductance converter (SEPIC) model and analyzes the results of implementation of zero-voltage and zero-current switching (ZV-ZCS). ZV-ZCS SEPIC converter has been simulated in MATLAB in buck as well as boost mode. A fabricated model of the SEPIC converter has been designed to be operated in ZV-ZCS mode. This converter has been designed with an aim of reducing power losses during switching of higher frequency devices, such that the overall efficiency of the system can be improved.
