| 摘 要： | 提出了一种高性能金属卤化物(MetalHalide,简称MH)灯用电子镇流器的电路拓扑。负载侧输出为低频方波电流,有效克服了MH灯声共振现象。高频开关管实现零电流软开关,提高了工作效率。采用起动和运行阶段不同的控制方法,实现了镇流器与灯特性的配合;给出了其相应的控制策略,并通过实验验证了该方案的有效性和可行性。

| Abstract: | A new electronic ballast with good performance is proposed to operate MH lamps in the paper.The output current is operated at low-frequency square to prevent the acoustic resonance for MH lamps.Because of ZCS operation,it can work in high switching frequency while achieving higher efficincy.The discrete controls in the starting and running phase are used to realize the matching of ballasts and lamps,the control strategy is detailed.The experimental results shown that the circuit topology is feasible and the theoretical analysis is right. |
