    • Designed for reliable and long operational lifetime under long-term full output.

    Tips: How to keep the voltage stable for permanent magnet generators?

    The principle of voltage stabilization of permanent magnet generators: By changing the conduction angle of the thyristor, the output voltage of the generator is kept stable.

    When the generator rotor rotates, the magnetic field generated by the permanent magnet on the motor rotor cuts the stator windings and induces an AC voltage. The voltage is rectified by the rectifier bridge and supplied to the electrical appliances for operation. The voltage regulator changes according to the voltage level of the generator. The conduction angle of the thyristor keeps the output voltage of the generator stable.
