1. In a phase controlled regulator an over-voltage interrupt circuit comprising in combination:

  • a sensing means for sensing the outputs of the phase controlled regulator and for generating a voltage proportional to the voltage difference between the outputs;

    a reference generator for generating a reference;

    a comparator means having the reference connected thereto as one input for establishing an upper threshold and having positive feedback establishing a resetting threshold lower than said setting threshold;

    an on/off controller means for controlling the on and off switching of said regulator;

    a first switching means for providing an override signal to said on/off controller which turns said regulator off in response to a sensed output above said setting threshold and turns said regulator on in response to a sensed output below said resetting threshold, thereby providing output voltage off/on sequencing between said setting and resetting threshold values in response to an over-voltage.
