A Soft-Switching Half-Bridge DC-DC Converter and Realization of Its Controlling Method
摘要
Abstract
In this paper, a soft-switching half-bridge DC-DC converter and its controlling method have been put forward. Based on the principle analysis of the half-bridge converter, an improved half-bridge circuit was introduced. An auxiliary soft -switching device was composed by utilization of auxiliary switch, inductor and two diodes. Controlled reasonably, the wide -range turn -on and off at zero voltage was achieved for the main power switch device, the switching loss and the voltage oscillation of the transformer secondary side rectification circuit were effectively suppressed. Meanwhile, the working efficiency of the converter was improved. The reasonability and feasibility of the proposed program have been confirmed in experiments and a high practical value was verified.关键词
