Abstract :
This paper presents the integration of power stages in order to supply HPS lamps with a low frequency square waveform. This waveform is chosen to avoid the acoustic resonance phenomenon occurrence. Conventionally, the electronic ballast to supply the lamp in this way should have three power stages: power factor correction (PFC), power control (PC) and inverter. In this work, a methodology to integrate these power stages is defined. Seven different topologies are proposed and their experimental results are obtained in order to compare each one.
