This brief proposes an improved averaged small-signal model of pulse-width modulated dc-
dc power converters operated in continuous-conduction mode, which includes a resistance …

LED lamps are projected as prospective successors of incandescent lamps with high
efficiency and a long lifetime. Therefore, there is a need to develop energy efficient LED …

Increasing voltage levels and realizing power-line communications are important parts of a
smart grid, and because of this, the need for intelligent, digital, and multi-functional …

This paper presents an ac-dc LED driver that consists of two-parallel inverted buck
converters. To buffer the twice-line-frequency energy, one inverted buck converter (also …

The triboelectric nanogenerator (TENG) coupling contact electrification and electric
induction is a landmark development in the field of energy and self-powered systems …

Automotive light-emitting diode (LED) matrix headlights require both high-power efficiency
and stable control of individual LEDs. The proposed power converter uses a buck–boost …

This study aimed to investigate the impact of mesa geometry on the light output
characteristics of AlGaN-based 275 nm deep ultraviolet light-emitting diodes (DUV-LEDs) …

This paper proposes a light-emitting diode (LED) driver based on a three-phase resonant
switched capacitor (SC) converter. The LED lamp employs chip-on-board (COB) technology …

Cascaded boost-buck PFC (CBBPFC) converters offer a wide voltage conversion ratio and a
near-unity power factor but require a large output electrolytic capacitor, leading to poor …
