An isolated flyback switch mode power supply (SMPS) light-emitting diode (LED) driver for lighting application that features a single-stage AC/DC converter with minimal number of components which help to cut its cost.Abstract:
This paper proposes an isolated flyback switch mode power supply (SMPS) light-emitting diode (LED) driver for lighting application. The LED driver features a single-stage AC/DC converter with minimal number of components which help to cut its cost. The LED driver is using a single switching transistor, without supplementary inductors, correctional circuitry, or clamping action, thus ensuring a low cost design. The SPICE modelled LED driver uses auxiliary voltage output to maintain the equilibrium of the system based on the feedback from the output. Simulation models report up to 95.44% efficiency.read more

Design and experimental evaluation of a single-stage AC/DC converter with PFC and hybrid full-bridge rectifier
TL;DR: The proposed converter can achieve soft-switching characteristics since the power switches and output diodes were operated with ZVS and ZCS conditions, respectively and the output voltage was twice higher than that of when the relay switch was opened.
