Need help Regarding “UPS’ as a final year project

Hi,

Hope so. You all will be fine.
We are two students of Industrial Electronics, in Final year. We are not so much good in our academics. We have chosen a final year project regarding UPS.
That's why we are seeking help. That what should we do that our project will become at least equal to the standard.
We can work on Micro-controller also. We need suggestions. If any one of you have an FYP report, then kindly inform me.
We are very much worried about this. Kindly help us.
Thanking you

Well, ideally your final year project should showcase what you have learnt. You can use someone else's project but then that would only help pass your exams.

To get you started, you can build a simple UPS with the following blocks:

1. A charger - this converts AC mains to a voltage suitable to charge the battery
2. An inverter - this converts the battery's DC into AC at the mains voltage and frequency
3. A changeover mechanism that detects loss of AC and switches the load to inverter instead of the mains, and also disconnects the battery from the charger

Here is an inverter circuit. If you have questions you may ask.

You can import more at "homemade circuits just for you from Swagatam innovations", it will greatly help you.

Nice invertor simple invertor circuit where did you get this from ? also have you got similar circuits for sine wave invertors in Other words sinewave out

Have you more complicated schematics to maintain secondary voltage

This has nothing to do with the above question by the way but I am personally interested in looking at schematics like this myself

In answer to your question Sami

Here is such a schematic

And here is a slighlty more complex diagram which should help you and give you some ideas s to where you might begin Easy if you understand this possibly not if you dont

Its not overly difficult I have worked on these before but you do need a good understanding of electronics to begin these projects


Possibly what would help you is having worked on dc to dc invertors TV power supplies , VCR power supplies , Computer power supplies and of course Amplifier power supplies which are nearly all Invertors

You could also include within this mobile pho9ne chargers , battery chargers and any other Dc power supply related to charging invertor equipment and also would definatley include micro programming ADC and various PGM langauges associated with this plus of course PWM


This ideally would be your background and experiance


This I would think would be the reference point for standards expected of you So there is quite a huge amount of background knowledge that you would need to attain Also bare in mind that this now vastly SMT technology as well


These are typical Industry standards

Hope it helps you

In, the recent days, many engineers are trying to improve their knowledge and skills by creating new projects. Electronics field is one of the essential things and prove themselves as good electronics engineering as they have to do a lot of hard work in completing the project. So, we are find there some list of mini electronics project ideas for final year engineering projects.

Thanks for sharing with us.
