DC Motor Based AC Power Generator Design and Implementation

Abstract

A reliable and efficient electricity supply is a vital requirement for the development of any country as it is the primary source of energy that powers most technologies. This document describes the design and implementation of an alternator that produces electrical energy from an alternator that uses a DC motor as its prime mover. The generator armature shaft was directly coupled to a DC motor driven by a high-current battery. The DC motor spins the alternator armature in the field coil at high speed when energized. This will give you two AC output voltages from the alternator he 12 V and 220 V he. The 12 V output was fed back to charge the battery using a diode and the 220 V output was used to drive an AC load connected to the generator. The 12 V output constantly charges the battery as the DC motor consumes energy from the rechargeable battery. The system is also equipped with control and display circuits to automatically switch the generator on and off, monitor grid and generator output voltages, and select the optimum output power for the load. It also has a built-in buzzer to issue an alarm and disconnect the load when an abnormality is detected.
