An interleaved DC-DC converter includes a non-gapped coupled inductor with first, second, and third windings. The converter also includes first, second, and third legs in parallel. The first leg has silicon carbide or silicon nitride switches, and the second and third legs have silicon switches. A controller modulates the switches of the first leg at a frequency greater than a frequency of the switches of the second and third legs.
