Abstract

This paper presents single-stage high-power-factor electronic ballast for metal halide lamps. By integrating two buck-boost typed power-factor- correction converters, a full-bridge inverter and a bidirectional buck converter, a single stage electronic ballast with symmetrical circuit topology is derived. The proposed electronic ballast can output a low frequency square-wave voltage to drive metal halide lamps. The problematic phenomena of acoustic resonance can be eliminated.
