Abstract
This paper presents a class D power amplifier used as an electronic ballast topology that can be used to supply one or more high pressure sodium lamps. It is ideal for poles luminaries with one or more High Pressure Sodium lamps used in private or public lighting. The proposed ballast supplies the lamps using synthesized waveform with fundamental frequency below 1 kHz in order to avoid acoustic resonance and minimize luminous flux oscillation. Control strategy, design guide line and experimental results are also included in this paper proposal.
