METHOD OF STABILIZING OUTPUT VOLTAGE OF A MAGNETOELECTRIC ALTERNATOR Russian patent published in 2020 - IPC H02P9/02 H02P9/30 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used in power supply system of independent objects. Method consists in that variable voltage MEG is rectified with variable rotation frequency of its shaft and at change of shaft rotation frequency from ƒ_min to ƒ_max it is regulated in direction of stabilization at the specified level, unregulated main rectified voltage U_d0 and additional rectified voltage ΔU_d0 are formed, these two voltages are summed in accordance with the expression U_d0Σ=U_d0±ΔU_d0, and stabilization of this resultant rectified voltage U_d0Σ is carried out by controlling additional rectified voltage ΔU_d0 by level and sign in range ±ΔU_d0=(+)ΔU_d0max÷0÷(-)ΔU_d0max, note here that voltage ΔU_d0 is summed up with main voltage U_d0 in range of frequency variation from ƒ_min to ½(ƒ_min+ƒ_max) and subtracted from it in range from ½(ƒ_min+ƒ_max) to ƒ_max. Substance of the method is explained by structural-functional diagram (HMEG).

EFFECT: improved weight and size and energy parameters while simplifying the technical implementation of the method, which provides higher energy efficiency of the process of stabilizing its voltage, high technological effectiveness of its implementation.
