VOLTAGE STABILIZED MAGNETOELECTRIC ALTERNATOR Russian patent published in 2020 - IPC H02P9/02 H02P9/30 

FIELD: electrical engineering.

SUBSTANCE: magneto-electric alternator (MEA) stabilized as to voltage includes a synchronous machine with excitation from permanent magnets 1, rectifier unit on diodes 2÷10. Diodes 2÷7 form the main rectifying bridge. Diodes 2, 4, 6 are united by similar electrodes and form the main cathode group. Additional diodes 8, 9, 10 are also combined by cathodes, forming an additional cathode group, which by its anodes is connected to input terminals of main rectifying bridge and together with its diodes 3, 5, 7 forms additional rectifying bridge. Reversible booster channel (RBC) contains high-frequency voltage inverter (HFVI) 11 made as per half-bridge circuit with voltage divider at capacitors 12, 13 and on transistors 14, 15. Primary winding 16 of transformer is connected to output HFVI and located on magnetic conductor 17. Two secondary windings 18, 19 of transformer together with transistors 20, 21 form two chains: "transistor 20 – winding 18" and "transistor 21 – winding 19". Some ends of these chains are combined, and one of their ends is connected to filter throttle 22 LC, the second end of which forms output terminal 23 of MEA. Its second output lead 24 is formed by connection point of anodes of diodes 3, 5, 7 of main rectifying bridge. Second ends of these chains are connected to connection points of the main and additional cathode groups. Capacitor 25 LC of filter is connected between terminals 23, 24. HFVI supply circuit is connected to outputs MEA 23, 24. Elements 11÷21 form a reversible booster channel (RBC), and elements 18÷21 form a reversible voltage transformer (RVT). Control of transistors 14, 15, 20, 21 is carried out by control unit (CU) 26.

EFFECT: technical result consists in improvement of efficiency and improvement of its specific index.
