VOLTAGE REGULATORS
Voltage Regulators
Summary
Voltage regulators are summarized below.
Voltage Regulators Summary
Purpose - to maintain the output voltage of a generator at a desired value
Sensing circuit - senses output voltage of the AC generator
Reference circuit - maintains a constant output for reference, or desired, voltage
output of the AC generator
Comparison circuit - compares reference voltage to output voltage and provides
an error signal to the amplification circuit
Amplification circuit(s) - takes the signal from the comparison circuit and
amplifies the milliamp input to an amp output
Signal output circuit - controls field excitation of the AC generator
Feedback circuit - prevents overshooting or undershooting of the desired voltage
by slowing down the circuit response
