VOLTAGE BOOSTER

摘要

A device for providing a substantially constant D.C. potential output from a D.C. input which varies from higher than to lower than the output. The input line is connected through an inductive reactor and a rectifying diode to a storage capacitor. An intermittently conducting switching transistor closes a circuit from the input directly through the reactor. The switching transistor is controlled by two transistors connected in an oscillator circuit. The frequency and duty cycle of conduction through the switching transistor is controlled by the oscillator. The oscillator in turn is controlled by a mixing circuit which has inputs of both the source and storage capacitor potentials. The storage capacitor supplies a voltage regulator which may be conventional.
