Abstract
When a failure of current detection parts occurs while a synchronous machine is operating, the failure of the current detection parts is detected and the operation of the synchronous machine is continued. An open-loop control part for performing control without using the detected current values of the current detection parts and a closed-loop control part for performing control using the detected current values are included, and a failure of the current detection parts is detected while the open-loop control part is operating.
