Fulkerson, Edward; Lanning, Rodney K.; Telford, Steven

A device includes a u-channel shaped member and a printed circuit board including a plurality of capacitors. Each of the plurality of capacitors has a mounting surface mounted to the printed circuit board and an opposing heat transfer surface thermally coupled to the u-channel shaped member. The device also includes an output cable coupled to the printed circuit board and a return cable coupled to the printed circuit board. The device further includes a control transistor disposed inside the u-channel shaped member and a current sensing resistor disposed inside the u-channel shaped member.
