Title:
ELECTRIC CURRENT SUPPLY SYSTEM, ELECTRIC POWER SUPPLY SYSTEM, AND CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/084798
Kind Code:
A1
Abstract:
Provided are an electric current supply system, etc. that can be miniaturized, that can be applied to both a drive source that has a wide rotational speed range and a drive source that has a narrow rotational speed range, and that can suitably supply electric current. The electric current supply system receives rotational drive force from a drive source and supplies electric current to an electrical load device that has variable demand for electric current. The electric current supply system is provided with: a rotor that has a permanent magnet and that is connected to the drive source; a stator that has a winding, that has a stator core on which the winding is wound, and that is arranged so as to face the rotor; and a supplied electric current adjustment unit that, in accordance with electric current demand on the electric current supply system, changes the magnetic resistance of a magnetic circuit that is seen from the winding and that passes through the stator core, and thereby changes the inductance of the winding and adjusts the electric current that is supplied to the electrical load device.
