FIELD: electricity.
SUBSTANCE: device contains the asynchronous generator, on the stator of which there are two independent winding groups: the excitation winding and the working winding. The working winding is connected to the mains, and the excitation winding is connected to the output of the inverter. The backup power battery, the speed sensor and the mains are connected to the input inverter contacts. A charging device powered from the mains is connected to the backup power battery input.
EFFECT: conversion of mechanical energy into electrical energy with the output voltage frequency independent of the generator rotation speed.
