    Hi, i live is Pakistan and here the voltage ratings are 220 vac 50 Hz. A few days back we got a gift (chopper machine) that is rated 110 VAC 60 Hz.

    And now i have been assigned to run this chopper machine. And frankly speaking i have no idea to do that.
    So can anyone give me proper circuit diagram though which i can convert 220 VAC 50 Hz to 110 VAC 60 Hz with 200 watt power.

    That would be against the Terms of Service for this site.

    Oops I totally forgot that.
    But either case we can't use transformer because we also need 60 Hz frequency.

    Thanks this circuit would work if I needed frequency of 50 Hz. But I need frequency of 60 Hz.

    Just what is the "chopper machine" anyway?

    This discussion is close to violating the Terms of Service, but because of the nature of the application (it is not likely to be mistaken for an isolated power supply) we are allowing the discussion to continue.

    You only need a 220v to 110 transformer, there should be no need for a freq convertor.
    Especially if Universal motors.

    I reopen the thread, but if the TS still insists to using the transformerless power supply then our mods will close the thread again.

    I think post #10 would be the simplest, surely they have transformers in Pakistan?
    Especially for 200w.

    Thanks for reopnening the thread.
    I am beginner in this field. Before postong here when I searched on google, all there was a triac circuit or something similar. That is why I said transformerless. If it is possible with transformer than it is not a problem for. All I want is that my circuit would work.
    Thanks sir for reopenning the thread.

    Yes there are available.
    But I don't think that a 60 Hz rated appliance would work on 50 Hz supply(without getting damaged).
    I don't mind using transformer but again what about frequency?

    The motor in that appliance is most likely a universal type as Max stated. If so, it should be happy on 50Hz or 60Hz.

    See post #12. I agree that the appliance is unlikely to have an induction motor, making the referenced article inapplicable.
    Universal motors are tolerant of frequency.
