1. A power converter system comprising:
a printed circuit board having
a first connector for receiving low voltage control signals, and
a second connector for receiving input voltages from one or more power generators and transmitting output voltages to a power distribution unit;
a plurality of power devices being configured to manage the input voltages and generate the output voltages, the plurality of power devices mounted onto the printed circuit board, each of the plurality of power devices including:
a base on a first side of each of the power devices,
one or more through-holes through the base,
a plurality of contact assemblies extending from a second side of each of the power devices toward the printed circuit board, the second side opposite the first side, the plurality of contact assemblies include:
at least one contact to electrically connect each of the power devices to the printed circuit board, and
at least one contact frame that surrounds the at least one contact;
an enclosure mounted around the printed circuit board and the plurality of power devices, the enclosure having interior surfaces and exterior surfaces, the base of the power devices engaging the interior surfaces of the enclosure forming a conductive heat path between the power devices, the interior surfaces, and the exterior surfaces that conductively transfers heat from the power devices to the exterior surfaces, the conductive heat path between the power devices and the enclosure having a combined cross-sectional area taken transverse to a direction of heat flow that is at least half of a total surface area of the interior surfaces; and
one or more mechanical fasteners disposed through the one or more through-holes of each of the power devices to mount the base of each of the power devices to the interior surfaces of the enclosure to secure each of the power devices to the enclosure.
