hiii....
Can any one mail me some 12v(DC) to 230v(AC) 1000W 50hz pure sine wave inverter schematics.

plz mail to my mail id.

Inverters like this. Is quite expensive to build. If you purchase seperate parts. You will end up with a very expensive inverter. My advice is to purchase one. Try ebay. Why do you want to build one by your self?

 

thanks for the reply..
I just want to built one out of my interest..
Is it possible to build if the 12V is increased to 24V or output power is reduced to 750W.

 

Almost everything can be built And your question is well inside the scope of forum. Take a look at this Microchip ups reference design. Maybe you can pic something up. If this school work. Remember that that teachers also use google. And this will show up. It is OK to use it as a reference design. But do not take any credit for work done by others.

...50hz pure sine wave inverter...

You'll need to define what you mean by "pure", in terms of % or ppm error. There is no pure, only a ± specification. If you just need it to "look like" a sine wave, that's relatively easy. If you need ppm precision, it's really tough, as noted.

 

I need actually a home inverter that can drive tubelights fans and TV, the quality of sine wave that can drive these is enough for me..

 

The inexpensive "modified square wave" inverters would likely be fine for all these. These inverters produce a stair-step simulation of a sine wave. Even the very cheapest square wave inverters would work for lighting and fans. The TV might be sensitive. No way to know without trying.
