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
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.

This achieves the object of enabling the switching of higher currents at DC voltages that would lead to sustained arcing in a conventional relay when switched off.
