output control. Functions of Generator Control Systems Most generator control systems perform a number of functions related to the regulation, sensing, and protection of the DC generation system. Light aircraft typically require a less complex generator control system than larger ... multiengine aircraft. Some of the functions listed below are not found on light aircraft. Voltage Regulation The most basic of the GCU functions is that of voltage regulation. Regulation of any kind requires the regulation unit to take a sample…

Alternator Voltage Regulators Voltage regulators for DC alternators are similar to those found on DC generators. The general concepts are the same in that adjusting alternator field current controls alternator output. Regulators for most DC alternators are either the vibrating ... relay type or solid-state regulators, which are found on most modern aircraft. Vibrating-relay regulators are similar to those discussed in the section on generator regulators. As the points of the relay open, the field current is lowered…

Figure 9-37. Sulfuric acid temperature correction. Constant Voltage (CV) Charging The battery charging system in an airplane is of the constant voltage type. An engine-driven generator, capable of supplying the required voltage, is connected through the aircraft electrical ... incorporated in the system so that the battery may be disconnected when the airplane is not in operation. The voltage of the generator is accurately controlled by means of a voltage regulator connected in the field circuit of the generator…
