VOLTAGE REGULATORS Voltage RegulatorsSummaryVoltage regulators are summarized below.Voltage Regulators SummaryPurpose - to maintain the output voltage of a generator at a desired valueSensing circuit - senses output voltage of the AC generatorReference circuit - maintains a constant output for reference, or desired, voltageoutput of the AC generatorComparison circuit - compares reference voltage to output voltage and providesan error signal to the amplification circuitAmplification circuit(s) - takes the signal from the comparison circuit andamplifies the milliamp input to an amp outputSignal output circuit - controls field excitation of the AC generatorFeedback circuit - prevents overshooting or undershooting of the desired voltageby slowing down the circuit responseES-11 Page 4 Rev. 0
