How should I know which circuit I should go for..as in for eg: the paper chooses a full bridge inverter and a cycloconverter. Is there a specific parameter they focused on for choosing it? Will I be able to choose what kind of converter or inverter I need depending on the parameters?
It requires more work to get AC sinewave output. There are various methods such as filtering, or PWM. It's probably a toss-up as to which you would find easiest to construct, or to regulate, or which is most efficient.
So you must weight all factors to determine whether you want square waves or sine waves or modified sines. Your transformer step-up ratio may be different, depending.
* How much power do you need?
* Is your load variable or unchanging?
* Can your load tolerate 120V square waves?
* Is your load an AC motor (which runs best on sine waves)?
* Do you intend to sell electric power to the utility company?
Etc.
But as of now I think I am going to start from the input by fixing the ratings for my panels and the battery banks. The next stage I think is the transformation stage. So please tell me what should I consider for deciding the transformer design and further steps. I shall keep you posted about my work.
I am really grateful because you have helped me kickstart my project work. I hope to get further help from you.
Here is a simulation showing the basic concept of a square-wave inverter (greatly simplified).
The switching devices would be replaced by transistors / mosfets.
In regard to design and construction of a transformer, this thread may be helpful.
