Abstract

This paper presents the electronic ballast for the metal halide lamp with free voltage input and implemented for CDM-T[150W] lamp. HID lamps have a good color rendition, long life and good focusing capability but they have fickers by acoustic resonance when driven at high frequency. To reduce the acoustic resonance phenomena, the electronic ballast was designed for high frequency operation with the constant frequency sinusoidal wave of 75[kHz]. Finally, the experimental results on the ballast of CDM-T [150W]metal halide lamp with the propose methods are discussed.
