  • Operating circuit for coupling a synchronous machine with a voltage network and method for operating it
    Patent number: 11201558
    Abstract: An operating circuit and a method for operating a synchronous machine on a voltage supply network is disclosed. The operating circuit has a converter circuit with controllable converter switches and a controllable switching arrangement to switch the converter circuit between a start converter configuration and a direct converter configuration. The power supply network is connected to a converter output and the synchronous machine is connected to a converter input of the converter circuit. In the direct converter configuration, an AC voltage is provided at the converter output with a preset AC voltage frequency. In the direct converter configuration, the switching of the AC voltage between the converter input and the converter output takes place without intermediate rectification.

  • Procedures for the operation of an electrical circuit
    Patent number: 9455569
    Abstract: A method for operating an electrical circuit is described herein. The circuit includes a power converter having a plurality of switches and two capacitors that are parallel to the switches. The plurality of switches and the two capacitors are connected in series. The power converter has two AC voltage-sided connections and a measuring resistor is connected to the ground. A ground fault is detected by measuring a voltage drop in a measuring resistor.
