  • Multiphase electric circuit for shutting down a current conducted over respectively one AC power controller
    Patent number: 8576531
    Abstract: In one embodiment of the present invention, a multiphase electric circuit is disclosed for shutting down a current conducted over respectively one AC power controller. The neutral points of the voltage systems connected to the phases are not connected to each other via a neutral conductor. The AC power controller of each phase is provided with two thyristors. A single series connection is connected parallel to all phases, which series connection comprises a capacitor and a number of parallel-connected quenching switches corresponding to the number of phases. The capacitor can be charged up via a diode bridge and a transformer.
