This paper proposes a thorough methodology for thesteady-state characterization of input and output current ripplesin Continuous Conduction Mode (CCM) interleaved powerconverters, under inductance mismatch. The proposal analysestotal ripple for any number of phases, any inductance ratioand operating point. Furthermore, calculation of amplitude, rmsvalue and harmonic content of total input and output currentripples is stated. Simulations on a 5-phase boost converter and a 5-phase buck converter are conducted under different conditions to verify the presented method.
