Keywords:
Frequency control, light emitting diode (LED), power factor correction (PFC), total harmonic distortion (THD).
Abstract
LEDs are used for general lighting applications due to their high efficiency and longer life. The eventual goal of this paper is to achieve high efficiency under heavy loads with low ac line condition and under light loads with high ac line condition. The pulse duty cycle control method with pulse frequency modulation for an interleaved single-stage fly back ac–dc converter is proposed here. In the proposed method, the interleaved DCM fly back converter is implemented. DCM operation can accomplish high PF for wide output power range. As a result, the proposed circuit is validated by the simulation results using MAT LAB software. Experimental results show the functionality of the on the whole system.
