Abstract

In a current-density controlled source of high-voltage current fed from a low-voltage current source and supplying a high-voltage direct current to two output terminals, an error voltage resulting from the comparison of a constant reference voltage and the voltage appearing at the terminals of a resistor through which flows a current proportional to the current to be controlled acts on the amplitude of an alternative current signal produced by an oscillator, the amplitude variations of the signal produced by said oscillator causing the amplitude high voltage current supplied to said output terminals to vary.
