Flyback Converter, Peak to Average Ratio, Harmonics Injection Technique


An LED lighting system requires a driver for to the power conversion from ac voltage to dc regulated current output. The electrolytic capacitor is use in the LED driver. But life of electrolytic capacitor is less then LED. Here we use film capacitor instead of electrolytic capacitors. But it’s Maximum capacitance per Unit volume is lower Then electrolytic capacitor. The output current in above driver is pulsating. In this paper we use harmonics injection Technique for make output current constant.
