| Abstract: | An effective method of eliminating acoustic resonance in metal halide lamps (MHD) is put forward. When the low frequency sine wave is added to the control loop, the frequency of the lamp current is variable. So the standing wave does not occur in the arc tube. The best range of modulate frequency is chosen by Fourier analysis of Saber simulation. The simulation results are used for 400 W MHD. This method is effective in eliminating acoustic resonance and ensures the stability of the arc and the light. |
