In the last decades, the high-pressure sodium (HPS) lamp has been supplied in high
frequency in order to increase the efficacy of the lamp/ballast system. However, at some …

To avoid the acoustic resonance on operating metal halide lamps, an autofrequency-
searching method is implemented on the high-frequency electronic ballast. The proposed …

In this paper, a novel high power-factor electronic ballast for metal-halide (MH) lamps based
on integration of a buck-boost converter, a buck converter, and a full-bridge inverter is …

The availability of T5 high-efficiency (HE) and T5 high-output (HO) fluorescent lamp families
not only increases the number of commonly used tubular fluorescent lamps from 9 to 18, but …

This paper proposes a novel single-stage high-power-factor electronic ballast for metal-
halide lamps. By integrating two buck-boost converters, a full-bridge inverter and a …

This paper presents a numerical model of high-pressure sodium (HPS) lamps, including
acoustic streaming. The model is implemented in COMSOL and is based on the finite …
