Power module for an electric drive of an electric vehicle or a hybrid vehicle, inverter comprising such a power module

A power module for an inverter for operating an electric drive in an electric vehicle or a hybrid vehicle, the power module comprising:

• a plurality of half-bridges, wherein each one of the plurality of half-bridges each comprises a substrate, a plurality of semiconductor switching elements, a positive DC power connection, a negative DC power connection, an AC power connection, and a plurality of signal connections,
• wherein the plurality of signal connections are electrically connected to the semiconductor switching elements in each half-bridge such that the semiconductor switching elements are configured to be switched by the signal connections, wherein the power connections are electrically connected to the semiconductor switching elements such that the semiconductor switching elements are configured to permit or interrupt an electrical power transmission between the power connections;
• and
• a positive busbar connected to the positive DC power connection and configured to provide external contact-connection for the positive DC power connection;
• and
• a negative busbar connected to the negative DC power connection and configured to provide external contact-connection for the negative DC power connection,
• wherein the positive DC busbar and the negative DC busbar each extend from the plurality of half-bridges up to an intermediate circuit capacitor, and
• wherein at least one of the positive DC busbar or the negative DC busbar is formed in one piece outside of the intermediate circuit capacitor with respect to the plurality of half-bridges.
