Abstract: A first supporting element, e.g. a PCB, may have opposed sides. A heat sink body is mounted on one side of the first supporting element, and having peripheral surface(s) for heat dissipating electrical device. A first circuit includes the heat dissipating electrical device(s) mounted and operates at a first voltage level. At least one circuit board assembly is mounted on the other side of the first supporting element, and extends from a first end to a second end. It has a first end connector at the first end, for connecting the first end of the circuit board assembly to the first circuit, and providing a signal interface between the first circuit operating at the first voltage level and a second circuit operating at a second voltage level different or equal to the first voltage level.

Abstract: The invention in part, is a heat removal system or apparatus providing a method of mounting and electrically connecting heat dissipating electrical devices, preferably in a radial geometry while achieving good surface-to-surface clamping force, in liquid and or air cooled variants. A variation of the invention can provide arc safety for high power density applications. In specific embodiments, the invention also provides low inductance as a result of minimal loop area while also providing high voltage isolation between devices. The N-sided geometry and effective clamping methodology offer low mass and volume. A variation of the invention also provides a signal interface for driving power electronics devices. A unique cylindrical electrical device package with terminals can support capacitor, inductor and transformer integration in a common package. The various elements of the invention can be combined together to minimize size and weight, while addressing high voltage, noise and thermal management.
