一种可节电的高压气体放电灯的电子镇流器

摘要

设计了一种高功率因数、可节电的高压钠灯电子镇流器,并阐述了系统的设计原则.该电子镇流器包括功率因数校正、半桥逆变、开关电源以及控制电路等.实验结果表明该镇流器性能优良,节能效果明显,功率因数大于0.98.%A high power factor electronic ballast with the function of energy saving is designed; and the design principles of the system are described. The electronic ballast consists of an APFC, a half bridge inverter, a switching mode power supply and the control circuit. Experimental results show that the performance of the designed ballast is superior and its energy saving effectiveness is very high. The input power factor of the designed ballast is more than 0. 98.
