ABSTRACT:
A voltage stabilizer includes the series combination of a series regulator element and inductor and an inverter circuit connected across a direct voltage supply. The series regulator is controlled by a comparator which compares the stabilized output voltage with a reference voltage. A diode energized in the forward direction by inductive turn-off voltage appearing on the inductor is connected in shunt with the series combination of inductor and inverter circuit. A series combination of a diode energized in the forward direction by the inductive turn-off voltages appearing on the inductor and the parallel combination of a resistor and a capacitor may be connected in shunt with the input of the inverter circuit. The inverter may be of the push-pull parallel or bridge type. The inverter output may be inductively coupled with the series control element.
