| Abstract: | An AC/DC power supply for high power lighting LED is proposed.The power supply circuit schematic is analyzed and simulated in Matlab environment,and a 50W experimental device is accomplished.Experimental results prove that the power supply gains high power factor(PF) and high efficiency,while the circuit is fairly simple,reliable,and capable of adaptation to various LED characteristics and wiring topology.The simulation results aided by Matlab are in accord with the experimental results. |
