| Abstract: | Due to negative resistance characteristics of metal halide lamp (MHL) and in order to make MHL be reliably switched on power and work normally, on the basis of analysis to MHL piecewise linear model, this paper raised a kind of control strategy based on piecewise linear suitable for its negative resistance characteristics. According to the control strategy, a three-step type constant power MHL electronic ballast was made to carry out experiment. Experiment result shows that adopting electronic ballast with ... |
