    going off topic form my pwm quest.

    National news today advises that the low voltage we have been experiencing is going to continue.

    Is there anything such as a simple AVR I can make for my monitor that just keeps switching off. The voltage fluctuates between 185To 190 volts

    A power conditioner comes to mind. Basically a "tuned" transformer arrangement that maintains output volts stable(within limits). Need to look it up on the web( just to refresh myself on its operation). I recall it uses a particular type of core arrangement and winding with a capacitor to "tune" the unit at mains frequency.

    This sounds really interesting what would I look for on the internet?

    It is called a constant voltage transformer.

    Incidentally, the Data General Nova 2/10 minicomputers used a CVT and it did not require additional voltage regulation.
    In many instances I experienced brownouts when the room lights would dim and everything else would shut down, except the good ol' Nova 2/10.
