This paper presents a fully digital controlled power supply unit for the wireless controlled dimmable LED lighting system. The proposed power supply designed using fly-back converter, which is directly controlled by a microprocessor. Although the proposed circuit does not sense the AC input current and has not AC input voltage feed-forward, it can achieve high power factor. The proposed power supply...
This paper presents a single stage power supply for LED lightings. The proposed power supply designed using fly-back converter topology, which is directly controlled by a microprocessor. Although the proposed circuit does not sense the AC input current and has not AC input voltage feed-forward, it can achieve high power factor. The proposed power supply directly regulates the output power for LED...
