摘要

提出了基于自动电流整形器和单开关逆变器(如E类电源转换器)适当集成的统一功率因数、单有源开关ac - ac电源转换器拓扑结构，该拓扑结构适用于灯镇流器应用。给出了理想运行模式的描述和一阶分析。所设计的镇流器具有以下显著特点:输入功率因数统一，灯电流波峰因数低;单有源开关降低电路复杂度;并通过实验验证了该方法的有效性。

Single switch, unity power factor, lamp ballasts

Unity power factor, single active switch AC-to-AC power converter topologies based on proper integrations of automatic current shapers and single switch inverters such as Class E power converters are presented, which are suitable for lamp ballast applications. Descriptions of desirable mode of operations and the first order analysis are given. The proposed ballasts have the following salient features: unity input power factor and low crest factor lamp current; single active switch reducing circuit complexity; and lossless switching, all of which are verified by experimental results.<>
