Design & Implementation of Soft Switching Dc-dc Converter with High Voltage Gain for High Power Application
نویسنده
چکیده
A zero voltage switching (ZVS) dc–dc converter with high voltage gain is proposed. It consists of a ZVS boost switch cell converter stage and a ZVS half-bridge converter stage with resonant converter and all these stages are merged into a single stage. The ZVS boost converter stage provides a continuous input current and ZVS operation of the power switches. The ZVS halfbridge converter stage provides a high voltage gain. The principle of operation and system analysis are presented. The design of the half-bridge converter stage can be focused on high voltage gain. Therefore, high voltage gain is easily obtained. ZVS operation of the power switches reduces the switching loss during the switching transition and improves the overall efficiency. Index Terms Boost converter, coupled inductor, high voltage gain, reverse recovery, zero-voltage switching (ZVS).
