Sepic Converter Design and Operation

May 01, 2014 · An acceptable output current ripple is i o, pp < 0.5 A An acceptable output voltage ripple is V o, pp < 0.1 V c) Duty Cycle Calculation: The amount that the SEPIC converters step up or down the voltage depends primarily on the Duty Cycle and the parasitic elements in the circuit. The output of an ideal SEPIC converter is
