  • Pulse shift protection method for detecting a phase-to-phase short circuit in a drive and a drive for executing the method
    Patent number: 11558001
    Abstract: The present invention is directed at a pulse shift protection method for detecting a phase-to-phase short circuit in a drive for controlling electric motors, wherein the drive provides an output voltage to the electric motor, and wherein the instant, at which a short circuit detection function is executed, is chosen to minimize disturbance in the output voltage of the drive. The invention is also directed at a drive for controlling electric motors, said drive including a controlling portion for generating an output signal and an output portion connectable to an electric motor. The drive is provided for executing the above-mentioned pulse shift protection method.
