摘要： A current detector that detects, based on output signals of N coreless current sensors, where N is a natural number of 3 or more, currents flowing in N conductors in a circuit connected so that the sum of the currents flowing in the N conductors becomes zero. The current detector has a signal-current correlation acquiring section that acquires a signal-current correlation representing a correlation between the output signals of the N coreless current sensors and the currents flowing in the N conductors. Furthermore, a current calculating section that calculates the currents flowing in the N conductors based on the output signals of all the N coreless current sensors by using the signal-current correlation.

摘要： The magnetic pole position of a rotary electric machine is electrically derived accurately by reducing a voltage error due to a dead time while suppressing the influence on the operation efficiency of the rotary electric machine. A control device performs dead-time compensation, and performs current feedback control in a d-q-axis vector coordinate system using a magnetic pole position computed on the basis of an induced voltage produced by rotation of a rotor or on the basis of a response component to a high-frequency observation signal applied to the rotary electric machine. In the case where the rotary electric machine is controlled by deciding current commands Id*, Iq* in the d-q-axis vector coordinate system, the rotary electric machine control device controls the rotary electric machine such that the magnitude of an armature current Ia becomes equal to or more than a lower-limit current Ia_min prescribed in advance.
