VOLTAGE STABILIZED VALVE MAGNETOELECTRIC GENERATOR Russian patent published in 2021 - IPC H02P9/02 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineerin. A voltage-stabilized valve magnetoelectric generator containing a series-connected three-phase magnetoelectric generator with a variable speed of the drive shaft in the range from n_min to n_max and a rectifier unit made according to a three-phase bridge circuit in the form of a three-phase anode group of diodes and double first and second cathode groups of diodes, and also a booster channel, control unit, power supply for internal needs. In this case, the booster channel is made in the form of a single-phase voltage inverter, made according to a half-bridge circuit on transistors, shunted by diodes and with a voltage divider on capacitors, and the primary winding of a voltage transformer is connected to the output of the single-phase voltage inverter, made with two series-connected secondary half-windings, the connection point of which forms one output terminal of the booster channel, made with the possibility of connecting to the first output terminal of the valve magnetoelectric generator, while the ends of the first and second secondary semi-windings of the voltage transformer are connected between the first and second cathode groups of diodes of the rectifier unit. The control unit contains a reference voltage adjuster (U₀, an output voltage sensor of a valve magnetoelectric generator U_d, a signal amplification unit ΔU_d, a pulse width modulator, a logical node and a driver unit. In this case, the logical node of the control unit is configured to implement the voltage boost mode in the range from n_min to n_max.

EFFECT: increasing the efficiency and functional reliability of the valve magnetoelectric generator, simplifying its design, improving manufacturability and reducing the cost of its manufacturing process.
