摘　　要：本文提出了一种新型两级式低频方波金属卤化物灯电子镇流器。PFC级采用IR公司单周控制芯片IR1150S控制,DC-DC级与逆变级结合,与传统的三级式结构相比,节约了成本,输入功率因数可达到1。同时本文还提出了一种新型的金属卤化物灯启动电路,试验结果验证了其可行性。As development of the green lighting project. The high intensity discharge （HID） is drawing close attention due to its high huninous efficacy, good color endering, security, long life and working steadily. A novel two-stage ballast for metal halide lamp （MHL） is presented in the paper. PFC converter is based on IR1160S, DC-DC converter is integrated with inverter, compared with traditional ballast,lower cost,high input power factor is obtained, meanwhile, a novel star-up circuit for MHL was presented. Experimental results were given out to verify its feasibility.
