An electronic driver with higher efficiency for lighting system is proposed in this paper. In the proposed converter, two flyback topologies are connected at the input stage with different polarity in order to avoid the input diode bridge rectifier. The design of proposed converter for 50W light emitting diode lamp is presented. In the proposed flyback, the numbers of switching devices are minimized when compared to other converter configurations found in the literature, thus reducing the conduction and switching losses and thereby increasing the efficiency of the converter. The output stage is boost converter circuit. The proposed converter is simulated using SIMULINK and the simulation results are presented in this paper to validate the proposed converter.
