摘要： A turbomachinery driving apparatus using a dual inverter system and a method of controlling the same, wherein a main control unit for controlling the two inverters is omitted, and an external communication unit for transmitting signals representative of the mutual operational conditions of the inverters is made unnecessary, the exchanging of these signals being done simply, whereby the size, weight, manufacturing cost and the number of parts of the apparatus are reduced. First and second earth leakage breakers (ELB1, ELB2), inverters (INV1, INV2), pumps (4-1, 4-2) and motors (5-1, 5-2) constitute a full duplex feed water system. The inverters (INV1, INV2) are connected to each other by signal lines (S3) and adapted to exchange signals representative of their respective operational conditions and failure conditions and requirements for the operations of the partner systems. Out of the load condition detecting sensors, respective flow rate signal transmitting signal lines (S4, S5) are connected to the inverters directly, and pressure signal transmitting signal lines (S6, S7) in common.
