A winding synchronous machine having a moving object including an inverter circuit comprises : 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. The moving-object circuit control device may comprise : 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. Problems associated with using a rare-earth permanent magnet can be thereby overcome, and a winding synchronous machine including an excitation circuit in which ripples almost never occur can be implemented without using an extra power source.
