Abstract: An electric power dissipater assembly for an electrically-actuated turbocharger that includes: a power switch configured to be electrically connected to an electric power output of an electrically-actuated turbocharger; at least one resistor that is electrically connected to the power switch such that, when the power switch is in a closed position and connected to the electric power output, the at least one resistor is electrically coupled to the electric power output so that electric power provided by the electrical power output is received at and dissipated by the at least one resistor; a controller that controls whether the power switch is in the closed position or an open position; and a substrate that is physically coupled to the at least one resistor and that includes a coolant path that is used to cool the at least one resistor when coolant is received within the coolant path.

Abstract: A printed circuit board (PCB) including a first side and a second side; a conductive layer within the PCB between the first side and the second side; one or more first side electrical components that are physically attached to the first side and electrically connected to the conductive layer; one or more second side electrical components attached to the second side of the PCB and electrically connected to the conductive layer; and a thermally and electrically insulating dielectric layer, within the PCB between the first side electrical components and the second side electrical components, that prevents heat emitted by the first side electrical components from increasing the temperature of the second side electrical components.

Abstract: A power electronics assembly that controls an electrically-actuated turbocharger includes a printed circuit board (PCB) having a non-conductive substrate supporting one or more electrical components that attach to the non-conductive substrate on one or more sides of the PCB; one or more conductive layers that couple with the non-conductive substrate and conduct electrical current within the PCB; a fluid barrier layer applied to an outer surface of the non-conductive substrate or conductor layer; and a PCB housing, configured to couple with the electrically-actuated turbocharger, having a fluid cavity that communicates liquid from an internal combustion engine (ICE) to the fluid barrier layer separating the liquid and the PCB.
