摘　　要：针对采用Boost电路的前端交直流变换器中存在的启动冲击电流问题,提出一种三级启动冲击抑制电路。所提电路不但能够抑制启动瞬间出现的一次冲击电流,还能够抑制由于Boost电路开始工作而产生的二次冲击电流。详细分析了冲击电流产生的原因,提出一种新型的启动冲击抑制电路,经仿真验证,所提电路能够可靠抑制冲击电流,证明了所提电路的可行性。将电路被应用于1 000 W两级式金卤灯电子镇流器中,实验测试结果表明:所提电路可有效的抑制冲击电流,其中一次冲击电流接近于零,二次冲击电流可控制在10 A以内。A three-stage inrush-current suppression circuit is proposed to suppress the inrush current,which exits in the front-end AC/DC converter with boost topology.The proposed circuit not only can suppress the impulse current when powered on,but also can suppress the second inrush current caused by the working of the boost circuit.This paper analyzed the reason for the formation of the inrush current,and proposed a novel inrush-current suppression circuit.The simulations were done to prove the rightness and feasibility of the circuit and the circuit is used in a 1 000 W two-stage electronic ballast for the metal halide lamp.In the experiment,the impulse current is nearly 0 and the second inrush current is less than 10A.
