1. A high voltage d.c. supply which receives alternating electrical energy from a general single-phase distribution mains, comprising:

  • means for periodically tapping said energy from said mains during periods having a duration less than a half-wave of the alternating electrical energy to thereby produce periodically chopped high d.c. voltage synchronized with said alternating electrical energy;

    means for regulating said chopped high voltage wherein said regulating means includes a frequency modulator for modulating an oscillating frequency of a ripple generator and wherein said means for periodically tapping said energy includes a means for validating that said regulating means is operating.
