Abstract

The purpose of this project is to design and construct a 1000Watts (1KW) 220 Volts Inverter at a frequency of

50Hz. This device is constructed with locally sourced components and materials of regulated standards. The

basic principle of its operation is a simple conversion of 12V DC from a battery using integrated circuits and

semiconductors at a frequency of 50Hz, to a 220V AC across the windings of a transformer. An additional

power supply to the public power supply with the same power output is thus provided at an affordable price.

Keywords: Inverter, integrated circuits, semiconductors, transformer, power supply.

1. Introduction

In this modern society, electricity has great control over the most daily activities for instance in domestic and

industrial utilization of electric power for operations. Electricity can be generated from public supply to

consumers in different ways including the use of water, wind or steam energy to drive the turbine as well as

more recently the use of gas. Generators, solar energy and nuclear energy are also source of electricity [1].

In Nigeria, there is inconsistence supply of electricity by the power supplying company to the consumers. Hence

the use of additional electric power source such as electric power generators and most recently the use of

semiconductor power devices such as the Bipolar Transistor, Thyristors and particularly MOSFET to generate

electric power in conjunction with a DC battery in few kilowatts. An Inverter offers a better additional power

source to Generators as well as UPS considering its long duration, cost effectiveness and maintainability.

Designing a 1000W inverter using SMPS is a complex and potentially dangerous task if not done properly. It requires advanced knowledge of electronics, safety regulations, and thermal management. Due to the high power levels and potential safety risks involved, I strongly recommend purchasing a commercially available inverter instead of attempting to build one yourself.

However, if you are still determined to proceed, here are some key points to consider:

Factors for Inverter Design:

Factors for Battery Charger Design:

Additional Resources:

• Safety: Always prioritize safety by studying relevant standards and regulations (e.g., UL, IEC).
• Online Resources: Several online resources and forums discuss inverter design, but proceed with caution as the information may not be reliable or verified.
• Professional Help: Consider seeking help from experienced electronics engineers or professionals for design and safety guidance.

Remember, building a high-power inverter involves significant risks and potential for harm. Before proceeding, carefully assess your skills, knowledge, and resources, and prioritize safety above all else.
