What are the types of alternators in cars?

There are many forms of generators, including DC generator, AC generator, synchronous generator, asynchronous generator (rarely used), single-phase generator and three-phase generator. Its working principle is based on the law of electromagnetic induction and the law of electromagnetic force. Therefore, the general principle of its structure is to use appropriate magnetic and conductive materials to form a magnetic circuit and circuit for mutual electromagnetic induction, so as to generate electromagnetic power and achieve the purpose of energy conversion.
