  • Publication number: 20250189960
    Abstract: A computer-implemented method for simulating a multiphase electric drive having energizable strings, using a hardware-in-the-loop simulator for testing a power electronic control device with an integrated inverter is provided. The simulator, based on a mathematical model of the electric drive, computes the string currents in the strings of the drive, and an electrical reactive potential of the potential-free string terminal resulting from the drive reaction. The potential-free string terminal is set to the reactive potential by a voltage emulator. The method reduces the influence of inaccurately computed reactive potentials on the simulation by supplementing the mathematical model of the electric drive in the strings in each case by a virtual switch. The virtual switches in the open state reduce the influence of the measured string voltages on the computed current flows. The virtual switches in the strings of the electric drive are opened and/or closed by a switching logic.

  • Patent number: 12289159
    Abstract: A method for delayed cyclic forwarding of messages by a system includes: receiving, by an input side of the system, the messages to be forwarded; and sending, by an output side of the system, the messages to be forwarded to a receiving device. A check is performed to determine whether the difference between a current system time and a receive time of a message under consideration is greater than or equal to the delay time. In the event that the difference is greater than or equal to the delay time, the message that has been in the buffer memory for the next longest time being checked in the same manner, and the checking of the messages is continued until a difference smaller than the specified delay time is found for a message.
