Abstract: This project work proposes SEPIC converter topology for developing electronic ballasts, supplying high-intensity discharge lamps fed by a pulse width-modulation ac–ac converter, implemented with bidirectional switches. The lamp operates directly from the ac mains; thus, the drawbacks of the low frequency square waveform operation get eliminated. The features of the proposed solution are high efficiency, high power factor, low cost, and the absence of electrolytic capacitors. This paper includes the design of passive elements.
Keywords: AC–AC conversion, acoustic resonance (AR) phenomenon, ballasts, current control, high-intensity discharge (HID), ignition, lamps.
