Abstract
A power electronics converter includes a carrier substrate, and a converter commutation cell including a power circuit. The power circuit includes at least one power semiconductor switching element. Each power semiconductor switching element is comprised in a power semiconductor prepackage. One or more terminals of each power semiconductor switching element are connected to at least one conductive layer of the carrier substrate at an electrical connection side of the respective power semiconductor prepackage. The electrical connection side is spaced apart from the carrier substrate by a gap. At least a portion of the gap is filled with an electrically insulating material with voids. A peak rated power output of the power electronics converter is greater than 25 kW, and a converter parameter, which is defined as a product of a dielectric strength of the electrically insulating material and a maximum void size, is less than or equal to 10,000 V.
