Design & Implementation of Soft-Switching Boost Converter

This book introduces a novel soft-switching of boost converter by using ARCP method, which realizes the zero-current switching(ZCS) of the main and auxiliary switches and possesses the small power auxiliary circuit and full PWM capability. In the ZCS, the auxiliary switch is turned-on before the main switch is turned-on, the power circuit relies on the addition of an auxiliary switch, diode and inductor circuit to commutate the inductive load current from a main diode to an active device enabling a zero current turn-on of the main device. This book addresses the optimum selection of the auxiliary and main inductor control parameters for the boost converter with soft switching technique; the auxiliary inductor parameter is derived based on a minimization of the losses for both main and auxiliary switches.
