WINDING SYNCHRONOUS MACHINE HAVING A MOVING OBJECT INCLUDING AN INVERTER CIRCUIT, AND METHOD FOR CONTROLLING SAME

摘要

The present invention relates to a winding synchronous machine having a moving object including an inverter circuit, wherein a winding synchronous machine, including a winding synchronous motor or generator having a moving object including an inverter circuit, is provided, the winding synchronous machine being characterized by comprising: a moving-object inverter circuit connected to the moving object of the winding synchronous machine; and a moving-object circuit control device connected to the moving-object inverter circuit so as to control the moving-object inverter circuit. According to the provided winding synchronous machine, the moving-object circuit control device is characterized by comprising: a stator inverter voltage estimator estimating a high-frequency voltage of a stator inverter circuit; a field current reference generator generating a field current reference of the moving object; and an energy storage device voltage controller generating a current reference tracking a DC-link energy storage device voltage of the moving object. According to the present invention, the winding synchronous machine can be implemented while overcoming the problems associated with using a rare-earth permanent magnet, an extra power source is not needed, and an excitation circuit, in which ripples almost never occur, is included.
