Solid-state switch mode AC-DC converters having high-frequency transformer isolation are
developed in buck, boost, and buck-boost configurations with improved power quality in …

Three new bridgeless single-phase ac-dc power factor correction (PFC) rectifiers based on
Cuk topology are proposed. The absence of an input diode bridge and the presence of only …

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 ac-to-dc light-emitting-diode (LED) driver circuit. A
buck-boost power factor (PF) corrector is integrated with a flyback converter. A recycling path …

A single-switch nonisolated dc/dc converter for a stand-alone photovoltaic (PV)-battery-
powered pump system is proposed in this paper. The converter is formed by combining a …

This paper deals with the capability of pulse width modulation (PWM) dimming operation
added to the high-power factor-integrated buck-flyback converter (IBFC), which was …

In this article, an integrated parallel buck–boost and boost converter (IPB 3 C) is proposed
as an electrolytic-capacitor-less light-emitting diode (LED) driver. The IPB 3 C provides a …

This article presents a modified asymmetrical half-bridge flyback converter (AHBFC) to fulfill
the single-stage step-down ac-dc universal input voltage application. This topology is …

In this article, a high-power-density off-line light-emitting diode (LED) driver is proposed. The
proposed ac-dc driver is the novel integrated buck and boost converter (IBBC). Besides the …

This article proposes an LED driver circuit which is wide-range continuous dimmable for
high power lighting application. The proposed LED driver is based on single-inductor …
