I have a dc source of 16 volt, 0.49 Amps. Can anyone suggest me a circuit to convert it into 12 volt ac.

 

If it is a linear supply, you could have ~12vac on the secondary, if a simple transformer supply.
What type is the present supply?

Max,

Actually the supply is a conversion of 6 Volt AC to 16 Volt DC. This DC needs to be inverted to 12 Volt AC.

 

Is it a transformer you can add a small overwind to produce the 12vac with the existing 6v ?, usually approximately 12-16 turns.
Max.

 

No, transformer is not present in the circuit.

 

Well you will have to use an oscillator to generate the AC from DC, you will incur losses as a result.

Why not just use a transformer from 6VAC to 12VAD?

 

Why not just use a transformer from 6VAC to 12VAD?

That's what I would do. Just use a common transformer with a 12 VAC center tapped ( 6 - 0 - 6 ) secondary set up as a autotransformer to get the 12 VAC directly from the 6 VAC source.

 

Ok, I'll see and let you know further.
