Inverter ... Mr. Gary Lecomte

hello
hi every one
MR. Gary Lecomte
1000W-Power-Inverter-Circuit-Diagram

This inverter circuit is working for just 30 seconds
whats the problem with it
note : the Trans is 220 v / 15 Ah
please tell me what is the problem
is it from the trans ? or what ?

because i need inverter circuit to works on 15 or 10 Ah

Better post a pic, schematic or preferably both if you want an answer.

ur need 10 to 15 Ah batteries...

Hmm, a transformer rated in AmpHour? What the hell are you talking about?

Also, I would think without much thought, that you would need a bigger battery, probably 10x that size of 10AH to run a 1000W inverter at full power for any length of time.

I have a car battery, but battery is not a problem, the circuit works for thirty seconds only.
does the problem lie in the trans ? because the trans is 15 Ah.
Regardless of the circuit can you give me an inverter circuit 1000 - 2000 w work on small Trans ???

Transformers are rated in Amps, not Amp Hours.

Assuming you mean you are using a transformer that has a 12V 15A primary in an inverter, that is only 180 Watts. You cannot produce 1000 to 2000 Watts with such a small transformer. You would need at 1000 / 12 = 83 Amps to produce a 1000 Watt inverter.

Bob
and thanks for your info. (Amp) that i know

in any case that is what happened
to use trans 1000\12 that needs a large size
i want to get to the point i want an inverter circuit dose not need large size
and thanks for your interaction with me
i think you understand what i need
Thanks

If you are just going to put a 60Hz sine wave thorugh a transformer it is going to be large to get 1000 Watts. The other option is to use a much higher frequency to step up the voltage and make a PWM based inverter on the output side. The higher freqency allow yous to use smaller inductors / transformers.

If you are really interested, here is a paper about the technique I described:

inverter circuit isn't work
the fuse is exploded
if you can give me a clear diagram about an inverter circuit 1000 -2000 w
without huge transformers
because i need it

I will be grateful
