Abstract
This paper presents a digital controller of electronic ballast for the metal halide lamp. The proposed controller includes the control algorithm for soft starting, no load protection, overcurrent protection and dimming(or power control). The proposed controller, moreover, has the high frequency modulation scheme and the tracking algorithm to avoid acoustic resonance phenomena. For the math production with the low cost using the ASICs, the proposed controller has been designed with the EPLDs only, without any microprocessor. In this paper, the proposed control algorithms are described and the experimental results of prototype 150W metal halide electronic ballast are presented.
