Abstract

Official abstract text for this publication.

An apparatus according to an embodiment includes a unit performing control so that a current applied to a permanent magnet and a synchronous machine having magnetic saliency match a command value, respectively; a unit generating a zero torque current command value so that magnet torque and reluctance torque of the synchronous machine are balanced; a unit that generates the command value in which the zero torque current command value is corrected so that an AC component is generated in at least a q-axis current; a unit acquiring a value of an estimation voltage generated by the AC component of the q-axis current; and a unit calculating a magnetic flux interlinked from the permanent magnet to a stator coil of the synchronous machine.

First claim

Opening claim text (preview).

What is claimed is: 1 . An inverter apparatus comprising: a current control unit that performs control so that a d-axis current and a q-axis current applied to a permanent magnet and a synchronous machine having magnetic saliency match a d-axis current command value and a q-axis current command value, respectively; a zero torque current command value generation unit that generates a zero torque d-axis current command value and a zero torque q-axis current command value so that…
