Abstract

Design requirement and performance evaluation were carried out on an experimental electronic ballast for High Pressure Sodium (HPS) lamp. The ballast included a high voltage ignitor and dimming capability. It was used to drive and examine the high frequency characteristics of a commercial HPS lamp (NAV-T 150W (SON-T), OSRAM). The experimental results reveal that for the frequency range of this study (27 ÷ 75kHz), the lamp is free of the acoustic resonance problem. It was also found that for the present experimental conditions, the lamp is purely resistive and that the resistance is practically independent of the power level and operating frequency. The lamp exhibited stable operation over a very large dimming range, down to about 7% of nominal power. The 2.8kV ignition pulse was found to be sufficient for both cold and hot start up under the proposed operating conditions.
