I am so sorry for taking so long. I am back.
Back to the tutorial, I thought it wise that, starting with the construction of an inverter does not really signifies the explanation of the nitty-gritty of electronics component, as I have earlier talked about. But since I have mentioned it, I have to start it. I keep to my words.
I would combined both the tutorial on the design of an inverter and the explanation of the behavior of electronic component, because if you know how electronic component behave in AC and DC circuit, then you can design anything you can think of.
What is a Power inverter? In simple terms, A Power inverter converts D.C voltages to A.C voltages. What is the difference between A.C and D.C voltages? A.C voltages reverses its direction, from the positive side to negative side. How is the conversion from D.C voltage to A.C voltage achieved ? so simple. This is achieved by means of an electronic oscillator. What is an oscillator? An oscillator is an electronic circuit that produces oscillating signal usually periodic in nature , at a desired frequency. There are different kinds and types of oscillator; Hartley Oscillator, wien bridge oscillator, crystal Oscillator and so on…
In this design,the oscillator is the microcontroller chip. Less I forget, knowing embedded C programing language is a major prerequisite for programing the microcontroller. If you are yet to know the embedded C ,do not worry, all would be covered in this tutorial, all for free. You will also be needing Proteus simulating software, microchip IDE, and XC8 compiler by microchip. You can add your comment below to, to signify your interest in the embedded c tutorial, the simulating software and the Microchip IDE.
Below shows the stages of a simple power inverter.
*Osscilator circuit
*mosfet driver
*H-bridge
*Transfromer
*Filter circuit
*Feedback circuit.
As you can see, the oscillator is the first thing to consider. The oscillator determines the waveform of the output voltage, it also determines the frequency of the output waveform.
I can foresee that this is going to be long tutorial. I can do all the teachings in a day, but as I have earlier said, I am teaching from the basics. So, it is going to take a longer time.
For the oscillator, I will be using the PWM module of the Microcontroller.
Next tutorial, I will be explaining how the microcontroller works and how to use it as an oscillator. The microcontroller used, is the PIC 16F877A. please,before the next tutorial, read about the PIC16F877A for a more concrete understanding .your comments, questions and suggestions are all highly welcomed .Thank you. TUTORIAL 2 WILL BE READY ,NEXT WEEK TUESDAY.
