    :huh: I am looking for an understandable picture of how switching transistors off and on can turn into a sine wave. Inverters.What makes the south pole of the wave and how do you get a smooth sine from a square wave?
    Several other questions that are stumpin me,

    If you hook up a small windmill to a large enough resistor will it actually slow
    the rpm or reduce the current without slowing it down?

    What makes the controller in an alternator in a micro hydro turbine send the juice to a diversion load? What component reacts when a certain voltage is reached?

    Any good sites that show detailed pictures of rewinding alternators?

    Anyone know of a school or intensive course anywhere in the US that drowns
    the student in all things generator. Repair ,install,troubleshoot, all sizes.
    From a 5000 watt to a 50k gen. or anything like it? Thanks
