The difference between a DC generator and an AC generator

1、 Functional characteristics of DC generators
DC generators have the characteristics of convenient use and reliable operation, which can directly provide electrical energy for various electrical equipment that require DC power. However, there is a commutator inside the DC generator, which is easy to produce sparks and has low power generation efficiency. DC generators can generally be used as DC power sources for DC motors, electrolysis, electroplating, charging, excitation, etc. for AC generators.
2. Functional characteristics of the AC generator
An AC generator is a generator that generates alternating current under the action of external mechanical forces. This type of generator can be divided into synchronous AC generators and asynchronous AC generators.
Synchronous generators are the most common type of AC generator. This type of generator is excited by direct current and can provide both active and reactive power. It can be used to supply power to various load devices that require AC power. In addition, according to the different prime movers used, synchronous generators can be divided into steam turbine generators, water turbine generators, Diesel generator and wind turbines.
