HIGH DC VOLTAGE GENERATOR

摘要

"High DC Voltage Generator" The primary winding of a stepup transformer is energized by a time-varying current for inducing a high voltage pulse in the secondary winding of the transformer in response to a rapid change in the time-varying current. A plurality of first diodes and a plurality of capacitors are arranged to form a voltage multiplier for multiplying the amplitude of the high voltage pulse and storing the multiplied pulse on the capacitors to develop a high DC voltage. A second diode is connected in a circuit between one end of the secondary winding and ground so that a current may flow in a loop through the first and second diodes in response to the high voltage pulse and potentials of opposite polarities may develop across the secondary winding. The second diode provides a capacitance in series with the distributed capacitance of the secondary winding, thus reducing the total capacitance to permit ringing to occur at a desired harmonic frequency of the high voltage pulse.
