摘要
提出了一种软开关单周期控制AC/DC变换器,以Boost电路工作在电流断续状态为例,分析了该电路的工作原理仿真结果表明,该电路在整个输入电压范围内都能保持软开关特性。
A kind of soft-switching one-cycle control AC/DC converter is presented. The operating mechanism of the Boost circuit is analyzed in discoutinuous conduction mode. Simulation results verify that soft-switching can be realized in whole input voltage. Uni(?)y power factor and higher operating efficieney can be attained.
