ABSTRACT:
A voltage control system that provides an output voltage of constant value to a load. The control system includes voltage supply means for providing the output voltage to the load. A feedback circuit supplies a feedback current. A summing circuit algebraically sums the feedback current and a reference current to provide an error signal that changes as the feedback current changes. These changes affect the amplitude of the output voltage delivered to the load. The error signal is processed by a voltage adjustment means including an error amplifier that amplifies the error signal for use in making an adjustment to the output voltage so as to maintain its constant value. A gain increasing means responds to transient changes in output voltage to momentarily increase the error amplifier gain to shorten system recovery time to constant output voltage.
