Abstract
The electrostatic potential supply comprises an operating potential source (+V.sub.cc), a transformer (122) having primary (156) and secondary (172) windings, and a resonant frequency, and a high potential rectifier and multiplier (124). The electrostatic potential supply also includes a phase comparator (110) and a voltage controlled oscillator (114) having a free running frequency of substantially the transformer (122) resonant frequency. The phase comparator (110) generates a control signal related to the frequency difference between the signal from the secondary winding (172) and the signal from the primary circuit (110, 112, 114, 116, 118, 102-1, 2) to synchronize the voltage controlled oscillator (114) output frequency substantially with the frequency of the signal from the secondary winding (172). The voltage controlled oscillator (114) is coupled to the primary winding (156) to maintain the operating frequency of the transformer (122) substantially at its resonant frequency.
