Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A wound-rotor type synchronous machine with an inverter circuit-integrated moving part, comprising: a stator; and a moving part magnetically connected to the stator, wherein the moving part comprises: a winding; a moving part inverter circuit which is connected to the moving part through the winding; and a moving part circuit controller which is connected to the moving part inverter circuit for thereby controlling the moving part inverter circuit,…
