摘　　要：本文针对预热式荧光灯 ,提出了一种应用于电子镇流器的可以实现荧光灯工作需要的频率变化曲线的CMOS方波发生器电路。该电路用于电子镇流器的智能功率集成电路中的控制部分 ,不仅完成了荧光灯在预热、启动及正常发光各阶段的频率要求 ,而且具有结构简单、外接元件少、成本低、频率可调控等优点。WT10.5,10.BZ]In this paper, a new CMOS square wave oscillator circuit for the preheating fluorescent lamp will be described. This circuit is used in the control part of the ballast′s Smart Power Integrated Circuit(SPIC). It would realize the frequency variation curve, which will fit the ballast′s request. This circuit can afford the different stages of fluorescent lamp, i.e., the stages of preheating, igniting, and running frequency conditions, with some advantages of simple structure, fewer outside components, low cost, regulable frequecy. This method will also easily extend in the other fields, which need the power supply frequency changing with time.
