Acoustic Resonance Rejection via Voltage Modulation Method for HPS Lamps
2007 IEEE International Symposium on Industrial Electronics
A voltage modulation method in order to prevent acoustic resonance (AR) in HP S lamps is presented. Two voltage modulation techniques via P W M inverter are proposed. The first one injects harmonic components in the lamp voltage reference. The second one consist of high frequency voltage modulated by a low frequency waveform. These techniques allow the control of crest factor other than rejecting the AR.doi:10.1109/isie.2007.4375092 fatcat:iyxq74sdh5cmfczj2i5xpjyk4u
