具有非线性电压转换有源箝位正激变换器
Active-Clamp Forward Converter with Non-Linear Voltage Conversion
摘要
Abstract
An active-clamp forward converter with non-linear voltage conversion is proposed. By adding a flywheel diode and an output inductor on the secondary side of forward converter, the advantages of active-clamp forward converter are retained, the range of input voltage is widened because of increasing duty utilization ratio, and the conversion efficiency is improved because of realization of soft switching and reducing the voltage and current stress of diodes. A prototype converter with input voltage ranging from 50 V to 100V,an output voltage of 12 V is built to be verified by the correctness of the theoretical analysis and the feasibility of the proposed technique.关键词
