Abstract:
The present invention is devised to allow accurate determination on quality of a current sensor, and provide a current sensor reduced in size and cost and an inverter having the current sensor. A direct-current sensor  380  detects direct currents supplied to a plurality of inverters  300  and  301  for driving an alternating-current motor  200  in which winding wires of a stator are independent from each other in individual phases and a voltage is individually applied to the independent winding wires. The plurality of inverters has a P connecting wire  150  connecting P buses and an N connecting wire  160  connecting N buses. The direct-current sensor  380  has a core surrounding the P connecting wire and the N connecting wire to detect the currents flowing into and out of the P bus and the N bus. This makes it possible to employ a small-capacity current sensor, improve the sensor accuracy, and allow accurate determination on the quality of the current sensor.

Claim (Index 3):
An inverter with the direct-current sensor according to  claim 1 , comprising:\n an alternating-current sensor that detects alternating currents flowing into the individual winding wires; and a diagnosis unit that diagnoses a failure of the direct-current sensor and/or the alternating-current sensor based on output information from the direct-current sensor and an output signal from the alternating-current sensor.
