1. A power supply for providing high level D.C. voltage and having automatic arcing control and short circuit protection and recovery, comprising:

  • a source of low level D.C. voltage;

    a step-up transformer having low voltage primary windings, wound on a ferrite rod and connected to said source of low level D.C. voltage, and secondary windings wound on said primary windings in a manner so as to effectively comprise a filter having a pass band centered at a predetermined frequency;

    a voltage multiplier circuit connected between said secondary windings and an output circuit of the power supply; and

    an L-C feedback loop, which includes a portion of said primary windings and a solid state switching device connected to said source of low level D.C. voltage, to provide an oscillating input voltage to said primary windings at approximately said predetermined frequency under normal load conditions in the output circuit and to automatically reduce the frequency of oscillation when shorting or arcing occurs in the output circuit.
