PROBLEM TO BE SOLVED: To provide a high-performance inverter output current multiplexing device that can reduce the high harmonic ripple component of current. SOLUTION: An output circuit 20 consisting of multiplex coil winding transformers 21R-21T is connected to an inverter with switching bridge circuits 13a and 13b at R phase, switching bridge circuits 13c and 13d in S phase, and at the same time switching bridge circuits 13e and 13f in T phase. Then, an input coil winding 22a of each multiplex coil winding transformer is connected to the output stage of each switching bridge circuit and at the same time, the coil winding of a coupling reactor 28 as a means for eliminating high-frequency ripple is connected to the output stage of adjacent bridge circuits. |
