Automatic Voltage Regulator For Generator Circuit Diagram

Adjustable voltage regulator circuit using lm317.

Automatic voltage regulator for generator circuit diagram.

Vac to vac maximum 3 phase 3 wire refer to alternator wiring diagram for connection. Red capacitor generator circuit diagram avr mx mx is a three phase sensed automatic voltage regulator and forms part of the excitation system for a brush less generator. Its numerous variations are found in both portable generators and automotive alternators and are described in various patents such as general motor s us3376496 for 3 phase applications and honda s us6522106. Well this is a collection of voltage regulator circuits using the lm317 ic which is an adjustable voltage regulator.

Lm317 is a three terminal adjustable regulator from national semiconductors and it s input can range up to 40 volts. Mx341 is a two phase sensed automatic voltage regulator and forms part of the excitation system for a brush less generator. The fluctuation in the voltage mainly occurs due to the variation in load on the supply system. This type of circuit has been around for years.

The variation in voltage damages the equipment of the power system. Excitation power is derived from a three phase permanent magnet generator pmg to isolate the avr control circuits from the effects of non linear loads and to reduce radio frequency interference on the generator terminals. The automatic voltage regulator is used to regulate the voltage. Mx automatic voltage regulator avr specification controls and accessories voltage.

By margaret byrd august 28 2019. It basically consists of a main exciter which excites the alternator field to control the output voltage. Automatic voltage control figure 8 20 gives the schematic diagram of an automatic voltage regulator of a generator. Regulator schematic the diagram below shows a generic avr implementation.
