Inverter  Project


My Previous Inverter Project Experiences

Hello, in this project post, I’m going to use my previous experience to review to you why every subject, topic and theories done in school is really important.

Years ago, I did a project presentation in my school Jets club project day, about the principle behind inverter. Prior to the Jet Club presentation, I did a research. While I was still making my research, I came across certain topics and theories I never expected and took for granted concerning Inverters.
Obviously, every subject topic and theory found in your course textbook absolutely counts.

During this research, the first fascinating topic I never expected concerning the principles of inverter was Motion. Although Motion could be considered during the flow of current in a circuit, but that isn’t really the principle behind inverter anyway.

They principle thing I realize after studying Motion that concerned inverter was Oscillatory Motion.
This is really interesting, my teacher thought Motion and give references, we all discuss everything we knew about Motion in class. Yet, I didn’t realize that it was going to attribute as one of the topics on my Inverter project, until I implemented the research.

Thus, this simply means that as a student it is important to commence personal research, learn new things and not to rely on the subject teachers.
When you choose a desire topic and carryout a research about it, you will be dispose to new knowledge and findings that might be of great benefits to your society, career, teachers and friends.

The Principle Of Inverters

(Science project @ JetClub T.G.C MKD, August 2019. By: Barnabas Stanley)


Introduction


Inverter: Is an electronic device that changes direct current (DC) to alternating current (AC)
With the aid of solar energy, the use of Solar panels, batteries and Inverters have becoming very essential for provision of Uninterrupted Power Supply in various homes, schools, offices...

This enthralling technology encompasses of a 12DC (Direct Current) solar panel connected to a DC Battery through a charge controller for storage, while the inverter is connected directly to the battery to change the current from Direct Current to Alternating current. This is because 90% of electronic appliances/gadgets are powered by Alternating Current.
That’s how this technology works!

Principles Building Inverters


Oscillators – Oscillatory Motion is a kind of Motion in which a body moves to and fro, reversing its direction, and returning regularly to its origin position.

This described the kind of motion found in Oscillatory devices (also known as Inverter), while Electronic Oscillator is an electronic circuit that produces a periodic, oscillating electronic signal, often a sine wave or a square wave.

Oscillators convert DC from a power supply to an AC signal. Inverters are built with aid of a circuit called Electronic Oscillators.

Electronic component is any basic discrete device or physical entity in an electronic system used to affect electrons or associated field.

Electronic components are classified into three major distinct

Simple Circuit Showing How Inverters is built


I’m about to show you an example on how inverters works. From my previous project presentation I built an oscillatory circuit with two components.

Though, the circuit isn’t going to give accurately a Sine Wave Signal, it’s only for educational purpose.

In this project, I used one Passive and one Electromechanical Component.

#1.Transformer: (Passive Component) is an electronic device use for reducing or increasing the voltage of an alternating current. It consists of primary and secondary winding of coils.

If you’ve tried an experiment with a transformer you’ll noticed that, when an AC of 220V supply is connected to the primary winding of a 12volt transformer, the secondary winding will decrease the AC to 12DCV.

 Similarly, when a 12DCV supply is connected to the secondary winding, they primary winding will increase the DC to AC. This can be detected with the help of a voltmeter.

Haven’t done this, you’ll notice that the Voltmeter will read the DC constantly, while the AC reads and cut off at once.

This is because the transformer isn’t creating absolute oscillation in the circuit.
Meanwhile, I had to add another component in order to completely oscillate the circuit during this project at T.G.C MKD. Instead of adding an active component like transistor, I decided to use an alternative component.



#2.Electric Motor-9Volt: At first, I connected the primary winding of the transformer to a 60watts bulb. Secondly, I connected the 9 voltage Motor’s +Ve (positive) terminal to the –Ve (negative) terminal on the secondary winding of the transformer, then I also connected the –Ve terminal of the Motor to the –ve terminal of a 12DCV battery supply, I than connected the +Ve terminal of the transformer to the +Ve terminal of the battery

Finally, it works the connected bulb lighted. I connected a Voltmeter and its detected a constant voltage. It completely works.
