Abstract :
This paper presents the study of quasi-square waveforms in order to avoid the problem of acoustic resonances in lamps of high intensity discharge. The study consists in the analysis of the electric power waveform, mainly, the study of the effect of the power harmonics generated with the quasi square waveform over the arc discharge of the lamp. The incidence of the acoustic resonances is evaluated by means of the wave equation for a high pressure Sodium lamp model Lucalox LU-70. After, the harmonics of the power waveform are obtained by Spice simulations and compared with the characteristics frequencies evaluated for this lamp. The analysis of the results indicate that a low frequency it is possible to avoid the presence of acoustic resonances with this kind of waveforms.
