In the paper the closed-loop frequency modulated (FM) buck converter output voltage ripples are examined theoretically, using SIMULINK simulations and experimentally. A closed-form expression to calculate and analyze the peak-to-peak output voltage ripples in continuous conduction mode is derived and confirmed experimentally. The expression can appreciably simplify the analysis of the effect of FM on peak-to-peak output voltage ripples of FM buck converter. The effect of duty ratio and the output power on the output voltage ripples of the FM buck converter is also analyzed. Some useful recommendations to mitigate the ripples effectively are proposed.
