VALVE MAGNETOELECTRIC GENERATOR WITH INPUT POWER FACTOR CORRECTION OF ITS RECTIFIER Russian patent published in 2023 - IPC H02P9/02 

FIELD: electrical engineering.

SUBSTANCE: three-phase armature winding of the magnetoelectric generator is connected to the inputs of the main rectifier, which contains three AC chokes, one ends of which form its power input terminals, and the other ends are connected to the inputs of the main rectifier according to the three-phase bridge diagram, between the output terminals of which a fully controlled main key element and a chain of series-connected main separating diode and a storage capacitor, forming the main rectification channel are connected. The control unit includes a pulse generator and a main driver for controlling the main key element, equipped with an output voltage sensor and a load current sensor. The generator is made with (M-1) number of additional armature windings, equipped with (M-1) number of additional rectification channels. The power input terminals of each of the additional rectification channels are connected to one of the additional armature windings of the generator. The control unit is equipped with a pulse distributor, M number of comparators with control and clock inputs, as well as a node for processing feedback signals from a voltage sensor and a current sensor, and (M-1) number of drivers.

EFFECT: enhancement of functionality.
