hello everyone, i really need documents related sin pure vawe.
How to make an inverter 12DC-220VAC, 1kW, please help me
Thank for attendance

please help me

 

What kind of experience do you have? This is not an easy project. And commercial ones are available for probably less than you can build it for.

I'm with Bob. Just go buy one. Done. You cannot come close to saving money by making your own.

Why do you think you need pure sine wave?

 

A PWM design can give close to a pure sine wave but, as noted, building a 1kW unit will likely cost more than buying one.

Note that 1kW requires over 80A from a 12V source.

 

thank all, but i want to know principle about it. i need a doccoments related sine pure inverter

How about this ?

There's a superb utility called "Google" !

thank you Ramussons, I have a proplem " DC - DC converter stage" to converter 12VDC to 350V/1kW.
How to make it

 

A new requirement.

Open a new thread.

 

i think that it is part of the project

 

Is this a school/college project/assignment requiring just a design, or do you actually want/need to build this for real? If the latter, given your obvious inexperience you could end up killing yourself. 350V is not something to be messed with.

 

oh No!!!!. i can make a design 220V to 12V/100A. please don't worry for me about that. any way, thank everyone very much
