This paper proposes a thorough methodology forthe steady-state characterization of input and output currentripples in Continuous Conduction Mode (CCM) interleavedpower converters, under inductance mismatch. The proposalanalyses total ripple for any number of phases, any inductanceratio and operating point. Furthermore, calculation of amplitude,rms value and harmonic content of total input and output currentripples is stated. Simulations on a 5-phase boost converter and a5-phase buck converter are conducted under different conditionsto verify the presented method.
