Abstract

This paper discusses a unified model for the determination of the constraint equations to be used in the selection of feasible capacitors for DC to DC converters. The model is based on a generalized waveform of the current flowing through capacitors, which provides the maximum acceptable ESR as a function of the capacitance C ensuring the compliance with ripple and constraints determined by the application. Design examples are presented regarding the application of the proposed model to boost, buck-boost and SEPIC topologies.
