摘要

本文提出了一种改进的双晶体管正激变换器——有源阻尼双晶体管正激变换器。它是通过在双晶体管正激变换器的变压器初级侧并联有源阻尼电路来阻尼电源开关两端的电压，使变压器退磁，实现电源开关的零电压导通。对变换器进行了完整的分析和仿真，得出了一些重要的结果。

An improved two-transistor forward converter

An improved two-transistor forward converter, an active damp two-transistor forward converter, has been proposed in this paper. It is developed by paralleling an active damp circuit at the primary side of the transformer of the two-transistor forward converter to damp the voltage across power switches, to demagnetize the transformer and to achieve zero-voltage-turn-on of the power switches. Complete analysis and simulation of the converter are performed, from which some important results are obtained and given.
