Description
Summary:This paper presents an electronic ballast to supply a 70W high pressure sodium lamp. The electronic ballast consists on a single-stage converter that integrates a buck converter to provide power factor correction and two flyback converters to supply the lamp, with low frequency square waveform, in order to avoid the acoustic resonance phenomenon occurrence. It is proposed one study, qualitative and quantitative, of active converters to provide the power factor correction, and their integration with the bi-flyback inverter topology. Buck bi-flyback inverter topology is chosen to the implementation of practical experiments, in order to validate the present work.
