An automotive propulsion system has a transmission including an output shaft, a variable voltage converter including an inductor disposed within a housing of the transmission such that transmission fluid within the housing contacts the inductor to cool the inductor, and a controller that maintains a magnitude of current through the inductor to less than a limit value that is defined by a speed associated with the output shaft and a switching frequency of the variable voltage converter.
