Design considerations for single-stage electronic ballast with a dimming feature are
presented in this paper. When the lamps are dimmed out to a lower light level, the density of …

The authors compare and evaluate 1) the traditional frequency-control dimming method and
2) a recently-patented voltage-control dimming method in electronic ballasts for fluorescent …

Power density modulation control strategy is proposed for eliminating the striations in
dimming applications. In a modulation period, the lamp is operated in several states. For any …

This paper proposes high-power-factor electronic ballast for fluorescent lamps. The
converter offers a high input power factor and a high-frequency supply to the lamp using a …

A single-stage high-power-factor electronic ballast is designed to drive the fluorescent lamp
in a wide dimmable range. The electronic ballast with an embedded buck-boost converter …

This paper presents a single-stage electronic ballast for driving multiple fluorescent lamps in
which a dimming control scheme is proposed to regulate the lamp current. A laboratory …

This paper presents a single-switch electronic ballast with continuous input current charge
pump power-factor correction. The ballast circuit is composed of a series/parallel inverter, a …

A simple design method has been developed to investigate the dimming control of electronic
ballast circuits for fluorescent lamps. This method is based on the steady-state calculation of …

With the global concerns on the issue of how to conserve the limited energy resources,
compact fluorescent lamps (CFLs) have been forced in a lot of countries to replace the …

An electronic dimming ballast with a lead-lag tank operation (LLTO) having the properties of
high efficiency and low stress is introduced in this paper. The ballast is configured with a …
