In this paper, a novel methodology is proposed to reduce output voltage ripple (OVR) of the single-ended primary-inductor-converter (SEPIC). The mathematical analysis of the SEPIC converter is performed to compute suitable values of capacitance and switching frequency for optimal reduction in the OVR. The OVR in SEPIC converter is analyzed in the presence of two-dimensional effect: first by varying the values of the programmable capacitor using digital controller; second by changing the switching frequency of the switching signal. The comprehensive mathematical analysis of the OVR in SEPIC is performed for three modes. The obtained results of proposed methodology for the reduction of the OVR in SEPIC converter are verified through MATLAB simulation.
