Abstract: An electrical device, e.g., an inverter or converter, includes a first and a second printed circuit board. The first printed circuit board includes protruding tab regions, and a respective tab region protrudes into a respective recess of the second printed circuit board. Contact pins, e.g., of one or more plug connector parts, protrude into holes of the second printed circuit board.

Abstract: In an electrical device and method for producing a first and second electrical device from a construction kit, the electrical device includes a heat sink having a contact surface, on which a power module is arranged. A frame part of the electrical device is arranged on the contact surface, the power module is accommodated in the frame part, and the frame part is delimited by a bulge of the heat sink protruding at the edge of the contact surface.

Abstract: A converter assembly, a method for producing a converter assembly and a method for operating a converter assembly are described, in which a base module includes power electronics and control electronics. The base module includes a housing, particularly a housing part at least partially forming a housing for the power electronics and control electronics. The base module includes an electrical and mechanical interface, via which signal electronics are able to be joined to the base module with form-locking and/or force-locking, in order to form the converter assembly. The signal electronics include a housing, especially so that after being joined, the housing of the signal electronics and the housing of the base module together form a housing of the converter assembly. A setpoint value for speed and/or torque is transmittable electrically via the interface, the signal electronics having means for receiving, determining and/or inputting the setpoint value.
