<span lang="EN-US">This paper focuses on a single-switch buck-boost (SSBB) converter for light emitting diode (LED) lighting applications. The proposed LED driver with power factor correction (PFC) shows enhanced performance in terms of input factor, efficiency and reduced voltage stress across the switch. presented is operated discontinuous conduction mode (DCM). PFC carried out using av...

Electric vehicles contain various types of light emitting diode (LED) devices. A significant twice-line-frequency ripple current is usually produced in a conventional offline LED driver with high power factor. In this paper, flicker-free based on isolated Cuk converter integrated magnetic technique proposed. Two inductors and transformer are combined into one core to eliminate the wave as much ...

Abstract To meet the high-reliability requirements of switch mode power supply LED driver chips with constant on-time architecture, a detection mechanism circuit that can detect switching frequency architecture is proposed. The completes conversion from to output voltage through separate tracing technology. uses method error calculation eliminate interference jump on detection. design based 180...

The research proposed a novel LED driver with the functions of power-factor correction (PFC) and current balancing. A flyback converter Class-D series resonant were integrated by sharing an active switch to form single-stage circuit topology. played role PFC circuit. component parameters designed make operate at discontinuous-conduction mode (DCM). In this way, input line can be sinusoidal, res...

LED luminaires need a driver circuit for working properly. Most of the drivers have disadvantages such as losses during operation. This issue becomes more important while supplying with limited sources renewables. To overcome problem, this study proposes novel energy efficient based on zero voltage switching (ZVS) single-ended primary inductance converter (SEPIC) technology. Driver and hence we...
