Simple inverter circuit

[pidja105]

Hello,
Can someone place here simplest circuit for inverter with one or two transistors without transformer with center tapped wire please.

 

[Alec_t]

What are the input and output voltage and current requirements?

 

[pidja105]

Input voltage is 12V, outuput 220V, current 390A or is better for first test power of 12W, in first post i mean I have a transformer, but I don't have center tapped wire.

Input voltage is 12V, outuput 220V, current 390A

390 Amps ???
Are you kidding ?!!

 

[pidja105]

390Amps from car battery INPUT.

 

[davenn]

my comment still stands

 

[pidja105]

But it can be smaller, I said 390A maximum.

 

[davenn]

no maximum mentioned

anything over around 50 Amps and a car battery would be flat in a few minutes or so

and anything over a few amps the circuit starts becoming more complex in its requirements
the best advice ... go buy one... it will save you a lot of stress and heartache

Sir pidja105 . . . . . .



There certainly must be an error in your "three hundred and ninety AMPERES" specification from the use of a car battery.
Which only in a fairy tale would convert up to 220 V @ 21 amperes at a mythical 100 % conversion efficiency rate.

We got the proper sizing of battery but it totally poses a problem in its mounting, using up the COMPLETE back of the car, but as you can see, the front end portion of the car is completely do-able.

Now for that more realistic power figure of 12 watts, thats only in the order of 12 volts @ 1 ampere . . . . .

to yield a 220V @ 50 milliamperes at a mythical 100 % conversion efficiency.

So, you see why we question the first high amperage specification, and we don't even want to visualize the wiring gauges involved.

I think he's stating the current rating of the battery, not what his circuit will draw from it. His first test is to produce 12 W at 220 Vac. Correct?

I did consider that but rereading, it still doesn't read that way LOL

His first test is to produce 12 W at 220 Vac. Correct?

correct well that's the way that bit read as well but he was eventually aiming for a huge current output


whichever way .... he obviously doesn't have the knowledge or skills to handle high voltage and current

so I will close the thread
