Design And Construction Of 2kva Step Up Transformer With Input Voltage Regulation And Control Circuit


Abstract


This research presents a study on transformer installation, operation and maintenance. A transformer is a static electromagnetic device that transfers energy by inductive coupling between its winding circuits.The inconsistency of power supply in Nigeria has led to research in the quest of finding solutions in the power sector. This project deals with the design and construction of a single-phase inverter which can convert DC voltage to AC voltage at high efficiency and low cost. A low voltage DC source is inverted into a high voltage AC source in two different ways. First, the DC voltage is stepped up using a boost converter to a much higher voltage. This high voltage DC source is then transformed into AC signal using pulse width modulation. Another method involves first transforming the DC source to AC at low voltage levels and then stepping up the AC signal using a transformer. The second method is the one used in this project. The converted AC can be set to any required voltage and frequency with the use of appropriate oscillator circuit, transformers, and switching and control circuits. Incorporated into these systems are devices such as MOSFETs, diodes, resistors and batteries which work hand in hand to obtain the overall desired operation of an inverter. Problems were encountered and tackled in the course of this project design. This design is especially focused upon low power electronic appliances such as personal computers, television sets, etc. the design was first mathematically modelled; then simulated in Proteus and finally, the results were practically verified.

Introduction

1.1 Background of the Project

A transformer is a static electromagnetic device that transfers energy by inductive coupling between its winding circuits. In another way, a transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. Electromagnetic induction produces an electromotive force within a conductor which is exposed to time varying magnetic fields. A varying current in the primary winding creates a varying magnetic flux in the transformers core and thus a varying magnetic flux through the secondary winding.

This varying magnetic flux induces a varying electromotive force (e.m.f) or voltage in the secondary winding. Transformers are used to increase or decrease the alternating voltages in electric power applications. In simple terms, it is an electromagnetic device that steps up or steps down voltages. Making use of Faraday’s Law (discovered in 1831) in conjunction with high magnetic permeability core properties, transformers can be designed to efficiently change AC voltages from one voltage level to another within power networks (Gottlieb, 2012.).

A wide range of transformer designs are used in electronics and electric power applications. Transformers are essential for the transmission, distribution and utilization of electric energy. There are many sizes, shapes and configurations of transformers from tiny to gigantic like those used in power transmission. Some come with stubbed out wires, others with screw or spade terminals, some made for mounting in PC boards, others for being screwed or bolted down.

Transformers are composed of a laminated iron core with one or more windings of wire. They are called transformers because they transform voltage and current from one level to another. An alternating current flowing through one coil of wire, the primary, induces a voltage in one or more other coils of wire, the secondary coils. It is the changing voltage of AC current that induces voltage in the other coils through the changing magnetic field. DC voltage such as from a battery or DC power supply will not work in a transformer.

Only AC makes a transformer work. The magnetic field flows through the iron core. The faster the voltage changes, the higher the frequency (Edward, 2011). However, the output of transformers various from single to double or multiple.


1.2 Problem Statement

This work intends to design and construct 2KVA step up transformer with input voltage regulation and control circuit. Hence, the problems involved in step-up transformer would be solved to ensure efficient and reliable long-term operation. The work will implement a common design rules on a global basis which will be designed and through structured methodology applicable in all phases of transformer production including quotation, electrical and mechanical design, and testing.


1.3 The Aim and Objectives of the Project

The aim of this study is to design and construct 2KVA step up transformer with input voltage regulation and control circuit. The objectives are as follows;

  1. To design a step up voltage device
  2. A well designed and developed regulating and control circuit to monitor the incoming voltage.
  3. To develop a step up transformer with multiple output voltages
  4. To build and construct a workable centre tapped step up transformer with input voltage regulation and control circuit.
  5. To develop a step up transformer with multiple output voltages
  6. To build an economic transformer with multiple output

1.4 Scope and Limitation Of Project

The scope of this project is centered on design and construction of step up transformer with multiple output that has these tappings as follows 110V, 80V 12V, 6V. Therefore, the step-up transformer would only work properly for machines and equipment with voltage levels on 110V, 12V, 6V and 3V,

The limitation of the device is that it does not power equipment that is above the level of 110v.


1.5 Relevance of the Work

The relevance of designing the step-up transformer cannot be overemphasized. This is because most electrical or electronic machines and equipment usually comes in various voltages which is solely done by the manufacturer. Also, the voltages as applied to countries are also different. Hence, the step up transformer could be utilized here in Nigeria for different machines and other countries since it is made up of different voltage outputs.


1.6 Project Organization

The entire project is arranged in sections to allow proper report presentation and understanding. The first chapter: the introduction; defines some important concepts on the project and gives a brief description of the problems in the society which results in the need for underground cable fault detector, this also contains the objectives, scope and limitations of the project. The second chapter is the review of related literature which describes briefly the history and classification of developed fault location method. Chapter Three highlight design methodology. Chapter Four highlight on the implementation and testing. Chapter Five is all about the conclusions and recommendations.\

Conclusion

The inadequacy of public power supply in our country calls for a temporary or an alternative source of power supply to be used in case of contingencies. This project met the objective and purpose which is to design and construct a 2KVA inverter with a microcontroller based frequency meter that could be used domestically. The advantages include:

  • Low maintenance cost though power inverters have huge purchase/capital cost
  • No moving parts (as seen in generators)
  • Easy installation
  • No need for petrol or diesel
  • Inverters offer noise free operations
  • Power inverters do not emit dangerous gases during operations

This project could be used by many other electrical/electronic appliances so long as it is used according to specifications. The construction was done in such a way that it makes maintenance and repairs an easy task and affordable for the user, should there be any system breakdown.
