Over excitation
conditions are limited to a safe period by a protection circuit within the AVR. Provision is made for
the connection of a remote voltage trimmer, allowing the user fine control of
the generator's output.
An analogue input is
provided allowing connection to the Power Factor controller or other external
devices with compatible output. The AVR has the facility
for droop CT connection, to allow parallel running with other similarly
equipped generators.
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.
