METHOD OF STABILIZING OUTPUT VOLTAGE OF GENERATOR WITH MAGNETOELECTRIC EXCITATION Russian patent published in 2024 - IPC H02P9/32 H02P9/36 H02P9/40 H02K21/14 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used in magnetoelectric generators of self-contained power supply systems. Method of voltage stabilization of magnetoelectric generator consists in voltage stabilization of generator equipped with additional winding by changing magnetic induction of stator magnetic conductor. At that saturation of teeth of magnetoelectric generator in idling mode is provided and magnetic induction in stator teeth is changed. Change of magnetic induction in stator teeth during generator load to nominal is carried out by reducing current in additional stator winding, wherein counter direction of magnetic fluxes created by permanent magnets on rotor and additional winding on stator are provided. When magnetic induction in the stator teeth changes in the range of variation of the generator load from the nominal one and higher, a consistent direction of magnetic fluxes of permanent magnets and additional winding is provided. Method is realized by using a magnetoelectric generator containing a rotating rotor with permanent magnets separated by an air gap with a stator.

EFFECT: higher accuracy of control, wider range of load variation at stable output voltage and high efficiency due to change in magnetic state of stator teeth, on which magnetic flux is closed.
