1. A liquid-cooled rectifier assembly comprising:
a first bus bar having at least one cooling channel formed therein, adapted and configured to carry a cooling fluid therethrough;
a second bus bar having at least one cooling channel formed therein, adapted and configured to carry the cooling fluid therethrough, wherein the at least one cooling channel formed in the second bus bar includes at least one upper cooling channel and at least one lower cooling channel formed therein in an alternating arrangement; and
a first power diode array arranged between and in contact with the first and second bus bars;
wherein the first and second bus bars define outer walls of a fluid chamber such that the cooling fluid entering the fluid chamber is distributed, at least in part, around an outer surface of the first power diode array; and
wherein the first power diode array includes the outer surface as one of an upper surface or a lower surface, and exposed surfaces at which free passage of the cooling fluid occurs between the upper and lower surfaces of the first power diode array.
