Interleaved DC-DC converters provide high current capability and low current ripple due to the parallel operation of current channels making them attractive to control batteries and supercapacitors in electric vehicles applications. However, the dynamical model of the converter changes depending on the operating mode making its control very challenging. In this work a current control strategy for interleaved DC-DC converters which estimates the real value of the average current using the sampled current and uses a state linearization to provide the same dynamics disregarding of the operating mode is proposed. Analysis of the proposed control and results showing its performance are given.
