Abstract

An auto-stabilized high power current generator which comprises a controllable frequency oscillator connected to a rectifier by means of a circuit including, in series, an induction coil, a measuring circuit developing a signal representing the current flowing between the oscillator and the rectifier, and a comparator for comparing the measuring circuit signal with a reference signal, and which controls the frequency of the oscillator to cause an increase therein when the measuring circuit signal exceeds the reference signal. The frequency of the oscillator is regulated by a switching circuit controlled, in the event the detected signal is less than the reference signal, by a timing device, and in the event the detected signal is higher than the reference signal, by the pulses delivered by the comparator. The invention is particularly applicable for supplying power to a process involving a discharge in a rarified gaseous atmosphere.
