  • Power electronic device
    Patent number: 11652422
    Abstract: A power electronic device comprising a grid side (L1, L2, L3) connected to a capacitor bank (2) is described, the capacitor bank (2) being connected to ground via a switch. Such power electronic device should be used in different types of grid with low costs. To this end a varistor (5) is connected in parallel to the switch.

  • THYRISTOR RECTIFIER WITH IMPROVED SURGE CHARACTERISTICS AND ELECTRIC MOTOR DRIVE WITH A CORRESPONDING THYRISTOR RECTIFIER
    Publication number: 20210305910
    Abstract: The present invention relates to AC-DC conversion in power electronics. In particular, the present invention is directed at a thyristor rectifier, which may be employed in an electric motor drive. The rectifier includes three thyristors and three diodes, wherein the thyristors are connected to a positive rectifier output and the three diodes are connected to a negative rectifier output. The present invention also relates to an electric motor drive comprising a corresponding thyristor rectifier. In general, the present invention may be used in a frequency converter for an electric motor drive, but it can also be used in non-drive application.
