摘要
针对传统金卤灯附加点火电路存在的弊端,提出了一种新颖的启动控制电路。它能有效避免在全桥逆变输出的死区时间内点火,点火后没有足够能量维持辉光放电而熄弧等问题。仿真、实验结果验证了该点火控制电路的可行性。
In order to avoid some drawbacks of conventional igniter for Metal Halide Lamps,this paper presents a new control circuit.By the use of this new type of ignitor,the lamp will not be ignited in dead time of the driver signals of fullbridge inverter,which will do great harm to the life of the lamp,and it can also avoid the phenomenon that the lamp doesn＇t have enough energy for the transition of glow to arc, which will aborts the ignition.Experimental results verify the feasibility of this new type of igniter.
