摘　　要：半桥逆变电路是荧光灯电子镇流器常用的电路拓扑结构,它的核心是磁环驱动变压器。一体化紧凑型荧光灯(俗称节能灯)的很多不良问题,都是电路设计与磁环特性不匹配所造成。笔者分析了1种灯电路设计与磁环磁滞回线矩形比不匹配而引起灯闪烁的案例,深入剖析了前因后果并找到了解决办法。Half bridge inverter circuit is a popular circuit topology that is often applied to fluorescent lamp electronic ballasts. Its key component is the drive transformer. Many bad problems of compact fluorescent lamps are caused by the mismatch of circuit design and magnetic ring＇s features. The authors analyze a design that does not match the hysteresis loop of the magnetic ring and have caused the problem of light flicker, and then proposes the solution to this problem.

关 键 词：磁环变压器 停振 矩形比
