Abstract: PROBLEM TO BE SOLVED: To realize a large multi-parallel capacity unit of a self-arc- extinguishing semiconductor switch element 10 effectively utilizing the capacitance of a single element 10 with a small economic load. SOLUTION: A unit, having filter capacitors 11U connected to both ends of one parallel/multi-parallel conversion modules (10UP, 10UN) is used as a basic unit. Such basic units are connected in multi-parallel with respective phases. The respective basic units are wired as follows. A large floating wiring impedance 13U, intrinsic to the basic units is interposed between the basic units and DC terminals 2PT/2NT. A small floating wiring impedance 14U is interposed between the capacitor 11U and the conversion module (10UP/10UN) in the basic unit. The large floating wiring impedance 13U to DC terminal 2PT/2NT is intrinsic to each basic unit and is operated to correct a current balance of the basic units. However, since the electromagnetic energy storage thereat is absorbed by the capacitor 11U at turning off, it is not the load on a current cut-off capability of the switch element 10U.
