What is the difference between ac and dc generator

What is the difference between ac and dc generator, Main differences between AC and DC generators in Tabular form, major difference between an AC generator and a DC generator is that the DC generator requires a mechanism that provides a DC output.

In an AC generator, the energy produced in the generator is extracted directly through rings and brushes which are further connected to the output circuit. In the DC generator, the switch is mounted on the generator shaft through which the generated AC in the generator is converted to DC. The switch is connected to the output circuit by brushes.

The major difference between an AC generator and a DC generator is that the DC generator requires a mechanism that provides a DC output. This can be done mechanically with a switch or electronically with a rectifier. Internally, all generators produce an alternating voltage. All generators require a magnetic field.

Main differences between AC and DC generators in Tabular form

  • The AC generator is based on the principle of electromagnetic induction. Whether a conductor (coil) moves or a magnetic field moves, as long as there is relative movement between the conductor (coil) and the magnetic field, the conductor (coil) cuts the magnetic line of force and generates an electromotive force in the conductor (coil).
  • The DC generator is made according to the principle that the current conductor (coil) is forced to move in the magnetic field.
  • A copper ring (sliding ring) is connected to each end of the alternator current generator coil, it is an electric brush.
  • While the two ends of the DC generator coil are connected with a copper semicircle called a switch, which acts as a switch for the current of each winding and transforms the AC into DC.
  • The direction of the electromotive force of induction of the AC generator is determined by the right rule.
  • The direction of electromotive force of induction of the DC generator is determined by the rule on the left.
  • The AC generator enters mechanical energy and produces electricity, which means it is a rotary engine that converts mechanical energy into electricity.
  • The DC generator introduces electricity, produces mechanical energy, means that it is a rotation that converts electricity into mechanical energy.
