Abstract

By analyzing luminous process and volt-ampere characteristics of gas discharge lamp, a piecewise linear regress mathematical model is proposed. An illuminated loop-locked intelligent adjust light controller is designed by using power switching devices and SPWM variable voltage variable frequency controlling means. The above design can modify pulse and control carrier-to-noise ratio. Within a certain voltage range, it do better in dimming control of gas discharge lamp, besides it also effectively impair harmonic components of output signal and reduce its harmonic loss.
