DC / AC inverter, around 50W

[Mici]

Hi!

I'm a student and need a DC / AC inverter circuit for a practical work. Could you give me a hint, where to find a circuit around 50W?

Thanks!

Hi

THere are a project in Elektor. I think it is 150W but erally small and simple to build.
The output voltage will fluctuate depending upon involtage.

Thanks for the hint! Do you know in which issue of Elektor?

Hi

I think you can buy the article.

hxxp://www.elektor-electronics.co.uk/Default.aspx?tabid=28&year=2004&month=2&art=51715&group=Power%20Supply

But if you use a car battery then the voltage output will change with battery voltage.
Normally not very important but depends what you will use it for.

Hello

You can use oscillator, square or sine wave, drive two power transistors, to supply current to the secondary of a 50 watt transformer, you get the ac at the primary.

could u provide more info.?

like what app. do u use it for?

Google Royer Oscillator, it may be useful to u.

Hello

I have a circuit in 300 circuits book from elektor electronics, unfortunatelly, my home PC is out for maintainance, I will scan the circuit for you, but give me time to do so.
