Analysis and Design of Single-Switch Forward-Flyback Two-Channel LED Driver with Resonant-Blocking Capacitor

Analysis and Design of Single-Switch Forward-Flyback Two-Channel LED Driver with Resonant-Blocking Capacitor Abstract: In order to balance the light emitting diode (LED) current in each channel, many active and passive methods have been investigated. Among the various methods, the passive method using LLC converter with a blocking capacitor or flyback converter with a current sharing […]


A Novel Wall-Switched Step-Dimming Concept in LED Lighting Systems using PFC Zeta Converter

A Novel Wall-Switched Step-Dimming Concept in LED Lighting Systems Using PFC Zeta Converter Abstract: This paper presents the design, simulation, and implementation of a non-isolated discontinuous conduction mode operated Zeta-converter-based light-emitting diode (LED) driver with the novel wall-switched step-dimming concept to achieve power quality improvement at universal ac mains. The power-factor-corrected Zeta converter maintains constant […]
