    Hi everyone

    I need a circuit diagram for inverter which convert from 12vdc to 220 vac.

    and another one for 6vdc to 220 vac

    I need them simple with sinewave


    Thanks

    How much power must they supply? - that is the hard part.

    You really should have put this with the other thread. He defined 7W in the first thread.

    Sine wave invertors are not simple. You don't need it anyhow for a flourescent, and most comercial models aren't sine wave either. Like I said, a simple 555 oscillator with a transistor booster feeding a transformer would do it.

    Hi
    this is a 500W inverter, but squere wave. after transfarmar the wave shape is near to signe wave.

    Try it...... :)

    The circuit uses a 10A input fuse for 12V battery supply.:confused:

    For a 500W inverter, at least a 50A fuse is needed.

    Not with a 10A fuse it isn't. 12V X 10A = 120W max.

    You beat me to the post this time grasshopper, but next time it will be mine!

    It is an old square-wave inverter.
    The millions of parts making the oscillator can be replaced by a CD4047 IC one resistor and one capacitor.
