摘要:Two different Flyback configuration sat input PFC stage for lighting applications are presented in this paper. In both the converter configurations, the input PFC stage consists of two flyback converters with different polarity in order to avoid the input diode bridge rectifier. The design of the converters for 30 W light emitting diode applications is presented. The two converters are simulated using SIMULINK and simulation results are presented in the paper. A comparison in terms of losses and efficiency is carried out between the two converter configurations. A RCD snubber circuit is introduced in the input flyback stage of both the converter configurations to reduce the voltage stress across the switches due to leakage inductance at the primary side of the transformer. The output stage is boost converter circuit
