Abstract

In recent years, power generation and distribution has become a very rampant problem in our

part of the world. The main sources of power generation in Ghana is either Hydro-electric and

thermal energy which are so far being explored living wind, solar energy, and in some instances

combination of the above stated. In as much as this methods of power generation is very

complex, they are also very expensive and takes too much of time to implement. In that vein, this

project is to design An Electronic Power Generator for domestics use since in most cases the

power consumed domestically is not very large. In this project discrete integrated circuits and

other components are which makes its implementation less complex, inexpensive, and easy and

fast to install. The building blocks of the proposed project are storage system which supplies

voltage to the oscillators, system control, and the driver unit as well as the main output system.This oscillator (A) generates a frequency determined by the line constant. An output signal is

then fed to the driver (A) unit to amplify the signal which is then fed to the main output spring

system to re-amplify the signal from the 12V to 164V AC; it is the fed to the rectifier unit to

change the high voltage from AC to DC and filtered to produce pure DC voltage. A feedback

signal is fed to the oscillator (A) to control and maintain constant output. The 270V DC from

the rectifier is then fed through a fuse to the power output and feedback unit. Good power signal

from the filter and feedback unit is fed to the control system and another oscillator (B) to start

operation, the oscillator (B) then generate a frequency depending on the line constant for the

oscillator (B). This signal is then fed to the phase split driver unit to split the phases and then

drives four signals to the power output and feedback unit to drive four outputs two at a time

which then changes the 270V DC to 270V AC and a feedback signal is then generated from the

power output to the oscillator AGC (B) unit to set the power output to 220V AC st the frequency

of 50/60Hz, that is producing a regulated 220V AC from a 12V storage system for all electrical

appliances.
