AC Alternator

An alternator is a device that converts mechanical energy into AC electrical energy. A generator is a mechanical device which converts mechanical energy to either AC or DC electrical energyAn AC Alternator or generator is a electrical generator that converts rotary mechanical energy into electrical energy in the form of alternating current. This electricity is used to power schools, homes, hospitals, factories, telecommunications base stations and many other applicationsWhen the alternator pulley is rotated, alternating current (AC) passes through a magnetic field and an electrical current is generated. This is then converted to DC via the rectifier. Advancements in technology have meant that alternators have changed vastly in the last 50 years. an electric generator for producing alternating current.The advantages of an AC generator are that it can be stepped up or stepped down easily using transformers. It further reduces the transmission link size and reduces transmission losses. The losses in AC generators are less compared to DC generators. They have a compact design.
