The basic working principle of the generator is based on the law of electromagnetic induction and the law of electromagnetic force. Suitable magnetic and conductive materials are used to form magnetic circuits and circuits that conduct electromagnetic induction between them to generate. Electromagnetic power and achieve the goal of energy conversion. Generator refers to a mechanical device that converts other forms of energy into electrical energy. It is driven by a water turbine, steam turbine, diesel engine or other electrical machine. It converts energy generated by water flow, air flow, fuel combustion or atomic energy. nuclear fission into mechanical energy and transmits it to the generator. It is then converted into electrical energy by the generator.

The classification of generators includes: generators: generatorsdirect current and alternators; alternating current generators: synchronous generators and asynchronous generators Generator (rarely used); can also be divided into single-phase generators and three-phase generators.
There are many types of generators. In principle, they are divided into synchronous generators, asynchronous generators, single-phase generators and three-phase generators. In terms of generation method, they are divided into steam turbine generators, hydraulic generators, diesel generators, gasoline generators, etc. In terms of energy, it is divided into thermal generators, hydraulic generators, etc.

The small single-phase synchronous generator is widely used as a mobile power supply and emergency backup power supply. It has a simple structure, convenient maintenance and. reliable operation., high adaptability and other advantages, mbut the harmonic content in the output voltage is large under load and the rate of sinusoidal distortion of the voltage waveform is large. In the design of small single-phase synchronous generators, damping windings are often used to weaken the reverse magnetic field, improve the quality of the output waveform, and reduce the distortion rate of the voltage waveform.
