【摘要】 介绍了串鄄并组合式双管正激变换器的优点;分析了该电路的工作原理和有效占空比;推导出变换器的稳态特性。该变换器实现了两个开关管在零电压开关下导通和关断,另两个开关管在零电压开关下关断,最后在1kW的串鄄并组合式双管正激变换器的样机实验中得到了验证。更多还原

【Abstract】 The attractive characteristics of serial-parallel combined two transistors forward converter are introduced in this paper.The operation principle of the topology and the effective duty cycle are analyzed.The steady characteristic of the converter is derived.Two switches are turned on and turned off with zero-voltage switching,another two switches are turned off with zero-voltage switching in introduced converter.Finally,experiment results are given to verify the analysis.更多还原
