    Hi,
    New to the forum and looking for some help. I have a certain project that requires i design a circuit to convert 12V DC to 120 V DC however after searching around i have yet to find a solution. Any suggestions for a circuit for this would be very helpful.
    Thanks

    There are several ways of doing this, it depends to some extent on the power required.

    At present I am making a 12V to 300V supply based on a 4047 cmos chip driving two fets which feed into a transformer wound on a TV line output transformer core. I am hoping to get 20W out of this to supply radio valve HT.

    vinod chandran has a thread discussing this type of circuit.

    hi there :)

    do a google search on DC to AC inverters. they are readily available for producing mains voltage from a DC battery supply

    cheers
