| Abstract: | In conventional grid connected LED drivers, three stages are present, namely rectification, power factor correction and harmonic elimination. In this paper, a configuration is presented which uses a fully controlled full bridge rectifier (FCFBR) for rectification as well as power factor correction (PFC). This eliminates the need for PFC converters like fly-back converter. A Buck converter is used to drive the LEDs. Two Hysteresis controllers are used separately for harmonic elimination and power factor correction. The proposed configuration uses less number of components and a simple technique to meet general requirement of grid connected LEDs. The performance of proposed configuration is verified with simulation results. |
