Claim Text:
1. A power electronics device that is a frequency converter, the power electronics device comprising: liquid-cooled power units including at least one power semiconductor component that is an insulated-gate bipolar transistor (IGBT) or a diode, wherein the power units are mechanically separate; a substrate, among at least one substrate, and on which the power units are disposed, wherein the substrate includes liquid cooling ducts and is common to more than one power unit; an electrical interface connected to each power unit via a power circuit interface on a side surface of each power unit, and connected to the substrate via a supporting insulator on a top surface of the substrate, wherein each power unit is connected, via a liquid cooling interface on a bottom surface of each power unit, to a liquid cooling interface on the top surface of the substrate; electrical connectors on a top surface of each power unit for connecting to outside each power unit; and one liquid cooling interface and one power circuit interface on a side surface of the substrate for connecting to outside the substrate.
