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

摘要

The present invention relates to a wound-type synchronous machine having a moving object including an inverter circuit. The wound-type synchronous machine, which includes a wound-type synchronous motor or a wound-type synchronous generator having the moving object including the inverter circuit, comprises a moving object inverter circuit and a moving object circuit control device. The moving object inverter circuit is connected to the moving object of the wound-type synchronous machine. The moving object circuit control device is connected to the moving object inverter circuit and controls the same. The moving object circuit control device comprises a stator inverter voltage estimator, a field current command generator; and a voltage controller of an energy storage device. The stator inverter voltage estimator estimates the high-frequency voltage of a stator inverter circuit. The field current command generator generates the filed current command of the moving object. The voltage controller of the energy storage device generates a current command which follows the voltage of a DC energy storage device of the moving object. The present invention solves the usage problem of a rare earth permanent magnet; does not need separate power sources; and performs the wound-type synchronous machine including an energized circuit which a pulsating problem is rarely generated.
