    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.

    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?

    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.
