Abstract
A vehicle powertrain includes a direct-current (DC)-DC power converter and a controller. The DC-DC power converter includes first, second, and third legs in parallel, wherein the first leg is configured to carry a first DC current substantially equal to a sum of DC currents of the second and third legs. The controller may be configured to modulate switches of the first leg at a frequency greater than at least twice that of the second and third legs.
