Abstract

In this paper current ripple in output capacitor is investigated for a boost converter, two-lower-switch converter, 3-level converter with range switch, and totem-pole converter with range switch. Its effect on output voltage ripple and capacitor voltage stress is studied. Filter current ripples in output capacitors for these four topologies are compared and the method to select output capacitor according to the current ripple ability of the capacitor is discussed
