POWER OUTPUT DEVICE AND COMPUTER READABLE RECORDING MEDIUM RECORDING PROGRAM FOR MAKING COMPUTER PERFORMING ITS DRIVE CONTROL

摘要

PROBLEM TO BE SOLVED: To provide a power output device which can operate even if one of two inverters for controlling current flowing to two three-phase coils connected to a DC power source between neutral points becomes abnormal.

SOLUTION: In the power output device, a terminal 40A is connected to the neutral point M1 of the three-phase coil 10, a terminal 40B is connected to the neutral point M2 of the three-phase coil 11, and a terminal 40C is connected to a positive bus bar LN 1. A terminal 41A is connected to the neutral point M2 of the three-phase coil 11, a terminal 41B is connected to a negative bus bar LN 2, and a terminal 41C is connected to the neutral point M1 of the three-phase coil 10. The DC power source 30 is connected between wiring switching units 40 and 41. A control CPU 184 controls the wiring switching units 40, 41 to connect a switch SW1 to any of the terminals 40A, 40C and to connect a switch SW2 to any of the terminals 41A, 41B when any of the inverters 181, 182 is abnormal.
