摘要
本文提出了一种高性能的AC-AC变换器电路,用作无电极荧光灯的高频电子镇流器。它通过功率因素校正,并结合零电压开关的工作原理与脉冲频率调制的控制方式,提高了器件的功率因素,降低了功率开关的损耗,解决了两个功率开关的共态导通问题。文章对变换器的参数进行了分析与设计,并给出了一些实验结果。
A kind of AC AC converter circuit of high effiency is put forward in this article.It is used as the high frequency electronic ballast of electrodeless fluorescent lamp.It is adjusted by the power factor,and combined with the working principle of zero voltage switch and the control method of puls frequency modulation,thus improving the power factor of the device and reducing the loss of the power switch as well as resolving the connecting problems of two power switch.This article not only analyses and designs the parameter of converter,but also gives some results of the experiment.
