Abstract

In 40kHz-60kHz, the acoustic resonance band of 250W metal halide (MH) lamps is studied. The theoretical prediction and experimental observation show no same bands in which various MH lamps can operate stably. But the injection of approximate low-frequency sine wave modulation is effective method for eliminating acoustic resonance if the center operating frequency of electronic ballast is beyond 47kHz. Experimental results of ballast prototype support the proposed approach.
