    Theory about AC - AC Converter

    Hi all from Greece. I have to design a system which has these specifications:

    a) Input Voltage 220 Volts and 50 Hz

    b) Output Voltage 117 Volts and 60 Hz

    c) SPWM control

    d) The RMS of the Input Voltage has + - 10% fluctuations or variances.

    I cannot use transformer.

    Can you help me? Can you suggest me a good free site on Internet for studying this subject? Thank you.

    See this like starting idea :

    It will hardly implement the 50/60 Hz frequency conversion.

    Generally speaking, the hardware of a typical single phase motor inverter is what you need:

    Input rectifier, bus capacitor, PWM controlled H-bridge, output inductor, possibly a sine filter.

    If high input power factor is required, the AC/DC stage would use inductor plus H-bridge as well.

    Yes, I agree... Where can I find this theory on internet? Thank you. What I have to look for?
