The main objective of this project is to provide
uninterrupted power supply to a load, by selecting the
supply from any source out of 4 such as mains, generator,
and inverter and solar automatically in the absence of any
of the source.
In this project uses four switches to demonstrate the
respective failure of that power supply. When any of the
switches is pressed it shows the absence of that particular
source, switches are connected to microcontroller as input
The demand for electricity is increasing every day and
frequent power cuts is causing many problems in
various areas like industries, hospitals and houses. An
alternative arrangement for power source is a must.
The project can be further enhanced by using other
sources like wind power also and then taking into
consideration for using the best possible power whose
tariff remains lowest at that moment.
Microcontrollers are widely used in embedded systems
products. Microcontroller is a programmable device.
The Intel 8052 is, single chip microcontroller (µC) which
was developed by Intel in 1980 for use in embedded
Keil compiler is a software used where the machine
language code is written and compiled. After compilation,
the machine source code is converted into hex code which
is to be dumped into the microcontroller for further
processing. Keil compiler also supports C language code.
Power supply can be control in :-
supply can be controlled from four
different sources if any problem occurred in one
source then other sources can be used.
Cost of equipment is very high
Its very difficult to install and maintain the kit.
We conclude that main objective of this project is to
develop an “AUTO POWER SUPPLY CONTROL
FROM 4 DIFFERENT SOURCES: SOLAR, MAINS,
GENERATOR & INVERTER TO ENSURE NO
It has been developed by integrating features of all the
hardware components used. Presence of every module has
been reasoned out and placed carefully thus contributing
to the best working of the unit.
We can implement GSM technology to inform the
technician from which source power supply is
