A vehicle electrical power system includes a phase module assembly of a multi-phase inverter. The phase module assembly includes first and second flat laminated busbars extending in orthogonal planes. The phase module assembly also includes one or more transistors that convert direct current into one phase of a multi-phase alternating current of the multi-phase inverter, and to output the phase of the multi-phase alternating current to the load. The phase module assembly also includes one or more capacitors conductively coupled with the internal positive and negative terminal connectors and with the external positive and negative bushings configured to be conductively coupled with the power source of direct current. The assembly can be useful for vehicles because the components of the system are configured to carry large amounts of current in a more reliable and sustainable manner.

A cooled system includes an enclosure having an outer surface and an inner surface comprising a cooled enclosed area, multiple cable brackets thermally coupled to the outer surface of the enclosure, each cable bracket including a first surface conforming to the outer surface of the enclosure and an opening therethrough sized to hold a cable and conduct heat from the cable to the outer surface of the enclosure.

A multiplayer neutral bus that includes a plurality of conductive layers and a plurality of bushings is provided. At least a portion of the conductive layers are spaced apart from each other and form separate electrical flow paths. The conductive layers and bushings are arranged so that each bushing is electrically coupled to each of the other bushings. A method of installing the neutral bus is provided.

A turbine engine that includes an engine core, a core casing surrounding the engine core, at least one cowl surrounding the core casing, a power converter located between the at least one cowl and the core casing, an electrical generator disposed within the engine core, at least one electrical strut having an outer wall defining an interior and extending radially between the engine core and the core casing; and at least one electrical conduit located within the interior and electrically coupling the generator to the power converter.

The present disclosure is concerned with bus bars that are provided with protrusions that allow them to be brought directly or indirectly in contact with a cooling system to remove heat generated in the bus bars themselves. The disclosure further provides a method of cooling a bus bar. The method includes providing at least one bus bar with at least one protrusion, and connecting the at least one protrusion to a cooling element.

A heat sink for a high voltage switchgear includes: a body. The body is centered around a central axis that extends in an axial direction from a first outer surface of the body to a second outer surface of the body. At least one third outer surface of the body extends from the first outer surface to the second outer surface. At least one air channel extends through the body from the first outer surface to the second outer surface. The at least one air channel is surrounded by the at least one third outer surface.

An insulator for a bus connector arrangement including a first layer defining at least one first aperture, a first annular protrusion emanating from the first layer at one first aperture, a second layer defining at least one second aperture configured to align with each of the at least one first apertures, and at least one second annular protrusion emanating from the second layer at each of the at least one second apertures.

A bus bar module includes a bus bar that is formed of a plate-shaped piece of metal, a thermally conductive sheet that is in close contact with an outer periphery of the bus bar and that has an extension portion extending outward from the bus bar, and an insulating case that covers the bus bar and the thermally conductive sheet. An accommodation space S in which the extension portion is accommodated with a gap left between the extension portion and the bus bar is provided between the bus bar and the case. Through holes through which the accommodation space S is in communication with an external space are formed penetrating the case.
