Integrated Zeta-Flyback Electronic Ballast to Supply High-Intensity Discharge Lamps

This paper proposes a metal halide lamp electronic ballast based on the integration of zeta and flyback converters, which are used to achieve power factor correction and lamp current stabilization, respectively. The proposed integrated converter allows to reduce the number of ballast components with...

Description
Summary:This paper proposes a metal halide lamp electronic ballast based on the integration of zeta and flyback converters, which are used to achieve power factor correction and lamp current stabilization, respectively. The proposed integrated converter allows to reduce the number of ballast components without increasing the current stress in the shared switch. Thus, the lamp is supplied with a low-frequency square waveform that avoids the acoustic resonance phenomenon. The proposed topology has been implemented and validated by experimental results.
