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.
