This project involved the construction of a 2KVA inverter. It is an electrical/electronic device that converts direct current (DC) to alternating current (AC), potentially improving the society’s power supply.

This project was created to address the issue of power outages in society and to aid in the protection of electrical and electronic equipment used in the home or workplace. With the use of the appropriate transformer, switching, control circuit, and multivibrators, the converted AC can be at any required voltage and frequency.

Inverters are commonly used to supply AC power from DC sources such as solar panels or batteries, but a battery was used in this construction. The arm of the inverter’s construction is that when When there is a power outage or a failure from the power generating authority, the inverter will switch from a dc to an alternating current source, providing steady electricity.




Today, it is common knowledge that electrical power is unreliable. There is significant electrical power supply disruption all over the world. Many electrical equipments have developed problems or stopped working entirely as a result of the power outages. As a result, many businesses have been crippled, affecting the economies of many countries, including Nigeria. There is also an increase in the occurrence of power outages, which can be considered a form of pollution. As a result, high voltage spikes and brief voltage drops are common. These power outages can impair the performance of sensitive equipment in private and corporate organizations, resulting in critical data loss and even equipment damage.

It is not an exaggeration to say that Nigeria today has an epileptic supply.

The use of electricity. This has become the norm, and many Nigerians now regard power outages as “normal” and part of their daily lives. For this issue, a wide range of factors have been identified. Natural disasters, vandalism, inadequacies in sustainability, and a lack of local content are among them. The problem of poor quality power supply cannot be adequately addressed unless other factors such as a lack of political will to invest adequately in the power sector, a lack of replacement policy resulting in absolute equipment, unsustainable human capacity building, and an inadequate reward and remuneration system to motivate human resources to perform well are considered.

Over the last few decades, progress in developing alternative energy sources has demonstrated that independent power is possible.

system is not only feasible, but also extremely practical. In fact, a wide range of generating equipment is now available to enable individuals to benefit from any renewable source of energy. However, for a variety of reasons, most of their systems produce only direct current (DC) and frequently only at low voltages. Nonetheless, it is widely acknowledged that the greatest and most useful form of current is alternating current (AC), which is found in the vast majority of homes.

As a result, the ability to convert direct current (DC) to alternating current (AC) with a constant frequency that can also be used to power electrical circuits in homes or industries is required.


An inverter is an electronic device.

Inverters are electrical devices that convert direct current (DC) to alternating current (AC). The converted AC can be at any required voltage and frequency by using the appropriate transformer, switching, and control circuits. Inverters are commonly used to convert D.C sources such as panels or batteries to AC power.

A high power electronic oscillator, such as a 1000w, 220-24ov, 50Hz inverter. Because early mechanical AC to DC converters were designed to work in reverse, they were “inverted” to convert DC to AC. The inverter serves the opposite purpose of the rectifier.


In this project, a 2KVA DC to A.C inverter will be built and tested. The following are the primary reasons for undertaking this project:

1. Create an electrical system that can generate power from a 12V D.C battery and produce an output of 2KVA, 50HZ, 220-240V, which will be used to power electrical appliances.

2. The project also aims to introduce the HND student to basic electrical design and circuit construction.

3. The project (2000.00, 220- 240V Inverter) will also assist the student in understanding the fundamental principles of operation of an inverter circuit and its significance in society.

4. The project also aims to introduce the concept of circuit analysis.


The project, which is a 2000w, 240 – 240 Volt inverter, has four stages or units. These units consist of.

i. The power supply unit

ii. The inverter unit

iii. Unit of step-up transformer

iv. The Triggering Unit

The purpose of this project is to demonstrate how the supplied low voltage D.C power is used to power the circuit. It will also demonstrate how to convert a low voltage A.C. The step up transformer will convert the low voltage alternating current square wave to a higher voltage alternating current square wave. The triggering unit generates the triggering pulse required by the MOSFET to function.


The following components are used to build the 2000w, 220 – 240v, 50H2 inverter:

Resistors, capacitors, semiconductor diodes, transistors (MOSFET), and integrated circuits (ICS) are the major components used in the conversion of direct current (D.C) to alternating current (AC) (AC).
