Simulation and Implementation of Current-Fed Full-Bridge Boost Converter with Zero Current Switching for High Voltage Applications
This paper presents a current-fed full-bridge boost converter with zero current switching (ZCS) based on constant on-time control for high voltage applications. The proposed converter utilizes the leakage inductor and the winding parasitic capacitor resonant tank to achieve ZCS. In order to achieve ZCS under wide load range, the turn-on time of the full-bridge boost converter is kept constant and the output voltage is regulated via frequency modulation. The circuit is simulated using MATLAB and implemented using micro controller. Both simulation and hardware results are compared.
Keywords: Phase - shift resonant converter, Zero current control, Pulse width modulation control, soft switching.
