摘要: This paper presents a topology and its design methodology to street lighting system using light emitting diodes. The proposed has main application systems without energy consumption from the mains during peak-load time or emergency systems, supplying circuit by batteries when necessary. These applications are justified reduction in demand electric power increase reliability. LEDs supplied via with high factor integrated Buck-Boost Flyback converter, which is also used charge batteries. Besides, same supply through battery, reducing number of components. experimental results have been shown that it possible implement employing 20μF non-electrolytic capacitor. can be for other topologies applications.
