Abstract

PURPOSE:To eliminate the influence of the malfunction to an operating equipment by providing semiconductor breakers between the inverters of the respective power sources which have a plurality of inverters connected to a common DC power source and the breakers. CONSTITUTION:A plurality of inverters are connected to a battery 1, and semiconductor breakers 13 each of which has a conducting thyristor 14, a commutation thyristor 15, a commutation capacitor 16 and a gate circuit 18 are provided between the breakers 2 of the respective inverters and the inverters 5. A signal from a current transformer 9 is applied to a protecting circuit 10 at its malfunction time such as shortcircuit time or the like, which circuit 10 thus generates a gate block signal of the thyristor 14 or a firing pulse of the thyristor 15 or the like, thereby interrupting the thyristor 14. Accordingly, even if one of them shortcircuits in the direct current, it does not affect the other operating equipment but can separate the malfunctioned equipment, thereby preventing the instantaneous variation of the AC output voltage.
