摘要
针对新型电光源-金卤灯的负阻特性,本文介绍了一种金卤灯分段线性模型,并提出一种适用于金卤灯分段线性化启动特性和稳态恒功率控制的控制策略,设计了70W金卤灯电子镇流器样机以验证这种控制方法的可行性和实用性。
According to negative resistance characteristics of Metal Halide Lamp（MHL）,a piecewise linear model for MHL is introduced in this paper.A new special control strategy of electronic ballast to match the MH lamps properties has been given out.The feasibility and practicality of the control strategy is verified by a laboratory prototype of 70w electronic ballast.
