A block diagram of an astatic voltage stabilizer is given. The stability of the output voltage from this circuit is determined by the stability of the pedestal frequency f sub 0 and the operating stability of the frequency converter. The pedestal frequency is stabilized by using a quartz oscillator. However, the stability of conventional transistorized relaxation oscillators with magnetic coupling used as frequency converters is less than 0.1. Frequency, converters of this type are also limited in possibilities for controlling output voltage at a constant pedestal frequency. The author shows that these disadvantages may be overcome by using an inductive relaxation oscillator based on a tunnel diode.
