  • Publication number: 20220319976
    Abstract: A power module (2) including a molded package (4), three power terminals (6, 8, 10) protruding from a first side (40) of the molded package (4) is disclosed. The power terminals (6, 8, 10) include a positive DC terminal (6), a neutral terminal (8) and a negative terminal (10). The power module (2) includes a phase output power terminal (12) protruding from a second side (42) of the molded package (4). The power module (2) is a three-level power module including a plurality of control pins (14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36) protruding from the second side (42) of the molded package (4).

  • Publication number: 20220071066
    Abstract: The invention relates to an electronic power system (1) comprising at least one electronic power module (2). The electronic power module (2) comprises a base plate (3) and at least one heat generating component arranged on a first side of the base plate (3). The electronic power module (2) comprises a cooling structure (4) transporting heat away from the electronic power module (2) via a coolant that is guided by the cooling structure (4). The cooling structure (4) is arranged on a second side (5) of the base plate (3) opposite to the first side. Task of the invention is to provide an electronic power system (1) with an improved cooling. According to the present invention this task is solved in that the cooling structure (4) is integrally formed with the base plate (3).
