Abstract: A charger for an electric vehicle (EV) comprises a printed circuit board (PCB) on which power circuits defining respective phases of a multi-phase power conversion circuit are disposed along a first dimension, a conductive input bus bar mounted on a surface of the PCB and extending along the first dimension, a conductive output bus bar mounted on the surface of the PCB and extending along the first dimension parallel to the input bus bar, an input connector disposed at an end of the input bus bar, configured to receive input power for the plurality of power circuits; and an output connector disposed at an end of the output bus bar, configured to receive output power from the plurality of power circuits. The input bus bar and the output bus bar provide a substantially equal, low-resistance resistance path for current distribution to each of the plurality of power circuits.

Abstract: Some features of the invention include a LED luminaire, including a chassis having a chassis body, the chassis body having an inner perimeter and an outer perimeter. At least one LED lighting module is mounted on the chassis body. A LED power supply assembly includes at least one LED power supply unit for the at least one LED lighting module. The LED luminaire further includes at least one inner perimeter vent interposed between the chassis body and the LED power supply assembly to thermally separate the chassis body from the LED power supply assembly. Outer perimeter vents may be located along the outer perimeter. The inner and outer perimeter vents promote the natural flow of air around and through the LED luminaire to remove heat generated by the at least one LED lighting module and/or LED power supply assembly. In certain features, the LED power supply assembly includes top and bottom vent covers, and the at least one LED power supply unit is located between the top and bottom vent covers.
