How can I design a dc to ac inverter which will not use a transformer?

[Bharathi1]

Hi i have planned to design a dc to ac conveter with 12vDC input and 230VA output, Please guide me how can i design inverter without transformer?

Hi,

no transformer...

How is your plan to gnerate the high voltage? With 230V AC you need +/- 325V peak.

Is a step up converter with inductor allowed? If yes: then i´d do so.

There are some examples on google but should be tested.

But as far as i understand the inverter for AC mains, the transformer is required to step 12V AC to 110 or 220V. Auto transformer may work theoretically but the problem will be of isolation.
