1. In a power conditioner characterized by the use of a power factor correction stage having an output voltage, a voltage threshold circuit comprising:

  • a comparator with inputs and an output;

    a predetermined threshold voltage connected to a first comparator input and providing a first value to the first comparator input;

    a first signal corresponding to the output voltage of the power factor correction stage connected to a second comparator input and providing a second value to the second comparator input;

    a second signal corresponding to the output of the comparator and determined by a comparison of values of first and second comparator inputs; and

    a responsive means for altering one value in the group of first value and second value, in response to the second signal, changing the comparison of values of first and second comparator inputs.
