Abstract:
An object of the present invention is to provide an inverter driving device and an electric system which are capable of accurately detecting an offset amount of a current detection circuit that detects a motor current using a direct bus current, and compensating for the detected offset amount, to improve detection accuracy of the motor current and control the motor appropriately, without increasing the number of components of the inverter driving device. An inverter driving device of the present invention is configured to control driving of an inverter device that converts direct-current power supplied from a power source and outputs three-phase alternate-current power to a motor, in which the inverter driving device is configured to: detect a direct bus current flowing between the power source and the inverter device; calculate an offset current component to be superimposed on a detected value using the detected value where current values in two phases of the three-phase alternating current calculated in accordance with the detected value of the direct bus current substantially coincide with each other; and control driving of the inverter device in accordance with a current value for which the offset current component is compensated.

Claim (Index 3):
The inverter driving device according to  claim 1 , wherein\n the detected value used to calculate the offset current component is detected for approximately every 60 degrees or a multiple number of approximately 60 degrees of an electric angle of the motor.
