PROBLEM TO BE SOLVED: To attain switching loss reduction, noise level reduction and battery power supply voltage utilization rate improvement by reducing inductance of a power supply circuit in a redundant type electronic controller.SOLUTION: The electronic controller configured to control operation of a motor includes power modules 11a and 11b for driving the motor. Power supply terminals 32pua, 32pva and 32pwa of the power module 11a are disposed oppositely to power supply terminals 32nub, 32nvb and 32nwb of the power module 11b of a different pole from that of the power supply terminals 32pua, 32pva and 32pwa in the vicinity of the power supply terminals 32nub, 32nvb and 32nwb. Power supply terminals 32nua, 32nva and 32nwa led out of an end portion 311 of the power module 11a in a length direction are disposed oppositely to power supply terminals 32pub, 32pvb and 32pwb which are led out of an end portion 311 of the power module 11b, in a length direction, of a different pole from that of the power supply terminals 32nua, 32nva and 32nwa in the vicinity of the power supply terminals 32pub, 32pvb and 32pwb.SELECTED DRAWING: Figure 3 |
