This paper proposed one of various acoustic resonance reduction technique for three kinds of ceramic lamps (CDM-150, HCI-150, CMH-150). To reduce the acoustic resonance in the HID lamps, the researched results showed that the frequency modulated signal with the triangle waveform is very effective in order to drive th LCC type half-bridge inverter for HID lamp. Experimental results proved that the acoustic resonance could be rejected, if the adequate switching frequency band is selected and the driving signal frequency is modulated with a triangle waveform.
