What are the classifications of voltage regulators?

[Trenton]

The classifications of voltage regulators are: 1. Contact-type voltage regulator; 2. Transistor regulator; 3. Integrated circuit regulator; 4. Computer-controlled regulator. The working principle of a voltage regulator is: when the speed of the alternator increases, the regulator reduces the excitation current of the generator to decrease the magnetic flux, thereby keeping the output voltage of the generator constant. The maintenance methods for voltage regulators are: 1. Remove the protective cover and check the contact surface for dirt and burns; 2. Check the firmness of each connection, measure the resistance and the resistance value of each coil; 3. Check the closing voltage and reverse current of the circuit breaker, the limit voltage of the voltage regulator, the limit current of the current regulator, and the gap and air gap of various contacts.
