摘要
采用低频方波来驱动高强度气体放电(HID)灯电子镇流器可以有效克服声共振现象。叙述了低频方波HID灯电子镇流器的发展现状,介绍了几种低频方波HID灯电子镇流器的拓扑结构,对它们的性能进行了分析,并指出它们各自的优缺点。随着控制技术的发展,两级式和单级式低频方波HID灯电子镇流器将会有更大的发展前景。
Using low-frequency square-wave to drive high intensity discharge （HID） lamp can effectively overcome acoustic resonance phenomenon. Description was made to the present development situation of HID lamp electronic ballasts with low-frequency square-wave. Introduction was made to some kinds of topologies of HID lamp electronic ballasts, having made analysis for their performance, and pointed out each other＇s advantages and disadvantages. Following the development of control technology, twostage and single-stage HID lamp electronic ballasts with low-frequency square-wave will have more development prospect.
