| Abstract |
A Micro-controller-based dimmable electronic
ballast for HPS lamps is presented in this paper. An easier
and low-cost power control method is proposed in this
paper, based on the regulation of the average input current
of the inverter. Driving signal with low frequency
modulation generated from MCU is used to eliminate
unstable arc during dimming state. Experimental results for
the commercial HPS lamp Philips NAV250 show the
feasibility of the proposed ballast.. |
