to make a 100 watt inverter.

can i use a 12-0-12 5 amp step down transformer instead of a 12-0-12 10 amp step down transformer?

Hi Sahoo,

Since your are planning to build a 100 Watt inverter, you cannot replace a 12-0-12 10amp Tf with a 12-0-12 5 Amps tf.

 

If you do so your overall power rating will decrease. But if you are okay with that you can use it. Let us know what type of load you are planning for the inverter so that we can help you better

i have planned for 80wt electrical applainces. because i brought a battery bank of ratting 12v,7ah. so my overall project should be limmeted between 84wt. a 12-0-12 10a tf is unavailable in retail. so please tell me, what modification should i preferred so as to obtain a better efficiency? thankyou.

Since you have access to this 12-0-12 5 Amps transformer go with it. You can use this circuit.

Is it faithful to supply a load of 80wt on 5a, 12 o 12v transformer, with the battery12v 7ah.
In my inverter circuit I use a cd4047be I, irfz44n MOSFET is it work properly with giving better efficiency. Thank-you.

Sorry Sahoo it wont be able to give 80 Watts, it will just gv you 50 Watts.

Since a 10amp12 0 12v stepdown transformer is unavailable in retail. So i have a plan to make such transformer. So i want to know what is your basic recommendation for such transformer?
So that i will follow on that way. Is it a low cost deal? Thank-you.

Making yor own transformer is not an easy task. This would make your project complicated, I would recommend you to ship it from elsewhere.

It is difficult task to create your own transformer because you have to calculate properly the resistance, current & voltage ratio for the output and input purpose. Am agreed with "B.Aswinth Raj" to import it instead of doing effort with resultant zero.
