Abstract

Incandescent lamps and discharge lamps are generally used as light sources and special ballasts are needed thor stable operation of discharge lamps. In this paper, the author proposes the electronic ballast thor metal hallide lamps, experiments with high frequency square wave of frequency 22.52 KHz to avoid the acoustic resonance phenomenon and proves the usefulness of the proposed ballast. Furthermore, the author uses 220 AC voltage as a input voltage source of the proposed ballast. By examining the proposed ballast, lamp voltage of 139 V(max.) and lamp current of 1.4 A(max) can be measured. Furthermore, stable operation antral great luminouse fluxes are recognized.
