The main functions of the AVR are :
Potential Divider and Rectifier takes a proportion of the generator output voltage and attenuates it. The potential divider is adjustable by the AVR Volts potentiometer and external hand trimmer (when fitted). The output from the droop CT is also added to this signal. A rectifier converts the a.c. input signal into d.c. for further processing.
The
DC Mixer adds the Analogue input signal the Sensing signal.
The
Amplifier (Amp) compares the sensing voltage to the
Reference Voltage and amplifies the difference (error) to provide a controlling signal for the power devices. The
Ramp Generator and
Level Detector and Driver infinitely control the conduction period of the
Power Control Devices and hence provides the excitation system with the required power to maintain the generator voltage within specified limits.
The
Stability Circuit provides adjustable negative ac feedback to ensure good steady state and transient performance of the control system.
The
Low Hz Detector measures the period of each electrical cycle and causes the reference voltage to be reduced approximately linearly with speed below a presettable threshold. A Light Emitting Diode gives indication of underspeed running.
