Power electronics device
First Claim
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.

Abstract
Power electronics device, such as a frequency converter, which includes liquid-cooled power units (REC5, REC6, AFE5, AFE6, INU4, INU5, DC/DC, DC/AC) and also a substrate arrangement. The power units include at least one power semiconductor component, e.g. an IGBT or a diode, connected to at least one power circuit connecting them. The power units are mechanically separate and they are disposed on at least one substrate provided with liquid cooling ducts. The substrate is common to more than one power unit, wherein the substrate includes liquid cooling interfaces and power circuit interfaces for each power unit that can be connected to it. In addition, the substrate includes one liquid cooling interface and one power circuit interface (DC+, DC−) to outside the substrate.
