摘要： A power conversion apparatus is obtained which detects a mis-connection of optical fiber cables based on a difference in mode of feedback signals, and changes a phase sequence in an automatic manner only with the use of a logical composition of a microcomputer control section. A drive circuit (2) for driving a semiconductor device (1) includes a test signal recognition section (31) that outputs inherent feedback signals (32) in response to a test signal (30) from a microcomputer control section (3). The microcomputer control section (3) includes an optical fiber mis-connection detection section (29, 33) that detects a mis-connection state of the optical fibers (8) based on the inherent feedback signals (32). The optical fiber mis-connection detection section compares the inherent feedback signals (32) with the individual normal feedback signals stored beforehand, respectively, and detects a mis-connection state of the optical fibers (8)when it is indicated that at least one inherent feedback signal does not coincide with a corresponding normal feedback signal.
