DC generator automatic voltage regulator circuit is shown in Figure 7-53. This circuit is used to 40kW, 230V DC shunt complex machine, the voltage change rate up to 2.5 percent
. In Figure 7-53, BQ for the shunt winding, co} for the series winding in series with the external shunt resistor Rw winding circuit. Adjustment potentiometer RP, can change the generator output voltage setpoint.
