  "textContent": "The system has a control device (26) controlling short circuit of stator-side terminals (U-W) of a permanent magnet synchronous machine (10). Three disconnectable power semiconductors (T12, T14, T16) of the control device are electrically connected in a star connection. Idle terminals (48, 50, 52) of the semiconductors are connected to the stator-side terminals in an electrically conducting manner. A neutral point (44) of the connection is connected to direct voltage (DC) terminals (DC, DC+) of a self-commutated converter (8) by a high-ohmic resistor (46) in an electrically conductive manner. The power semiconductors are designed as insulated gate bipolar transistors or MOSFETs. The self-commutated converter is designed as a three-phase self-commutated converter.",
