BSTRACT
The energy that serves humanity without harming the environment is ecologically clean natural energy
that exists in nature. These types of energy include water, sun, wind, geothermal waters, geysers, waves,
rising and falling water levels, volcanoes, lightning, various currents in oceans and seas, biomass, hydrogen
fuel, urban waste, photosynthesis; may include photoelectric converters, chemical (galvanic) elements and
others. These types of energy are called non-traditional and renewable energy sources. It is possible to
produce clean ecological energy only from the above-mentioned energy sources. In the article, an
experimental study and analysis of the operating modes of an uninterruptible power supply using a wind
generator as a primary source

NTRODUCTION
Experimental studies of the working modes of the
developed UTM structures were conducted in the
laboratory of the Department of "Electronics and
Instrumentation" of the Fergana Polytechnic
Institute.
In the process of conducting experimental
research, a wind generator was selected as the
primary energy source of UTM.

An image of the developed wind generator is
shown in Figure 1.
Figure 1. General view of the wind generator.
This wind generator is low power (500W) and is
mobile. This wind generator has a compact
construction and can be installed in different
places and in a short time. Such wind generators
can be used for farms, low-power consumers, in
alarm systems, lighting systems of newly built
houses, in the use of computers, as well as as a
power supply source for telecommunications,
radio stations, medical systems, and household
radio-electronic equipment. intended. The use of
an electric generator based on permanent
magnets in the wind generator allows operation
without a step-up reducer, which in turn reduces
noise and losses and increases the reliability of
the device. The energy efficiency (coefficient of
wind performance) of airplane blades is 2-4 times
higher when they have a very flat surface [1-7].
Constituent parts of the wind generator. The
wind generator consists of the following parts:
the turbine of the wind generator; wind generator
mast (mast); the tail part of the wind generator;
wind generator blades; wind generator fasteners;
mast cables; turning mechanism [8-11].

Using a wind generator as the primary energy source of a mobile uninterruptible power supply, the
dependence of the UTM output power on the nature of the load was considered, based on which the power
transfer coefficient was calculated depending on the type of load [12-24].
