Abstract

A liquid-cooled power electronics unit includes a planar circuit board body having conductor tracks, a wet side with a wet space for carrying a dielectric cooling liquid, and a fluidically, separated dry side, wherein at least two high-voltage power semiconductors are arranged on the circuit board body on the wet side within the wet space, the high-voltage power semiconductors being cooled by the cooling liquid, and an electronic low-voltage circuit is arranged on the dry side of the circuit board body.
