  • Patent number: 11923798
    Abstract: In a drive system having an inverter and electric motor, and a method for operating a drive system, the electric motor is fed from the AC-voltage-side terminal of the inverter, a first series circuit, which includes a brake resistor and a first controllable semiconductor switch, is connected at the DC-voltage-side terminal of the inverter, and a second series circuit, which includes an impedance and a controllable second semiconductor switch, is connected in parallel with the first series circuit, e.g., in parallel with the DC-voltage-side terminal of the inverter.
    Type: Grant

  • Patent number: 10433452
    Abstract: In an electrical device, a model series of electrical devices, and a production method, in particular for a converter, having a circuit board including circuit traces, the circuit board has two similar and/or identical contact area arrays, the contact area arrays in particular transitioning into each other through rotation and/or displacement. A first contact area array of the contact area arrays is fitted with a first power module, and the second contact area array is able to be fitted with a second power module, e.g., so that a respective electric motor is able to be supplied from the respective power module.

  • Patent number: 10165692
    Abstract: An electrical device, for example, a converter, includes: a first circuit board, which includes first circuit traces and at least one plated-through hole, a second circuit board, which includes second circuit traces and at least one connection device, a power module, and a plug-connector part. The power module is placed on the first circuit board and is connected in an electrically conductive manner to the plated-through hole with the aid of the first circuit traces, the plug-connector part is placed on the second circuit board and is connected in an electrically conductive manner to the connection device with the aid of the second circuit traces, and the plated-through hole is connected in an electrically conductive manner with the aid of a cable to the connection device.
