Due to the high rise in luminous efficiency that high-brightness light-emitting diodes (HB-
LEDs) have experienced in recent years, many new applications have been researched …

This paper proposes a novel single-stage high-power-factor electronic ballast with
symmetrical half-bridge topology for fluorescent lamps. The proposed electronic ballast only …

A novel self-oscillating electronic ballast with dimming capability and high power factor
correction (PFC) is proposed in this paper. The single-stage electronic ballast integrates a …

In this paper, a modified valley fill (VF) circuit is employed to combine with a current-fed
resonant inverter as a passive high power factor (PF) electronic ballast. A conventional VF …

This paper proposes a novel single-stage high-power-factor electronic ballast via the
integration of a derivative buck-boost converter and a half-bridge resonant inverter. The …

This paper presents a design methodology and analysis of electronic ballast employing the
self-oscillating-command circuit. The self-oscillating electronic ballast is represented as a …

A single-stage high-power-factor electronic ballast with a Class-DE low-d v/dt rectifier as a
power-factor corrector is proposed in this paper. The power-factor corrector is achieved by …
