An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature. Occasionally, a linear alternator or a rotating armature with a stationary magnetic field is used. In principle, any AC electrical generator can be called ...

It uses a centre-tapped transformer to create a full-wave rectifier. Its biggest positive is that you only need 2 rectifiers to do this. Because of this, these were used when solid state rectifiers were still very pricey or you had to use valve rectifiers.

The rotor is a moving component of an electromagnetic system in the electric motor, electric generator, or alternator.Its rotation is due to the interaction between the windings and magnetic fields which produces a torque around the rotor's axis.

This rectifier configuration, like the half-wave rectifier, calls for one of the transformer's secondary leads to be grounded. In this case, however, it is the center connection, generally known as the center tap on the secondary winding.

A selenium rectifier is a type of metal rectifier, invented in 1933. They were used in power supplies for electronic equipment, and in high current battery charger applications until they were superseded by silicon diode rectifiers in the late 1960s.

Silicon controlled rectifier (SCR) is a type of thyristor.It is a four-layer solid-state current-controlling device.. SCRs are unidirectional devices: they conduct current only in one direction. Normally, SCRs can be triggered only by currents going into the gate.

Doubly-fed electric machine By feeding adjustable frequency AC power to the field windings, the magnetic field can be made to rotate, allowing variation in motor or generator speed. This is useful, for instance, for generators used in wind turbines .

Power electronics is the application of solid-state electronics to the control and conversion of electric power.. The first high power electronic devices were mercury-arc valves.In modern systems the conversion is performed with semiconductor switching devices such as diodes, thyristors and transistors, pioneered by R. D. Middlebrook and others beginning in the 1950s.

A full wave rectifier converts the exciter AC voltage to DC voltage. The armature of the exciter, the full wave rectifier and the field of the synchronous generator form the rotating components.

A rectifier is an electrical device composed of one or more diodes that converts alternating current (AC) to direct current (DC).A diode is like a one-way valve that allows an electrical current to flow in only one direction. This process is called rectification.

As synchronous machine is a constant speedy machine for a constant frequency supply, the output voltage of the machine depends on the excitation current. The control of excitation current for maintaining constant voltage at generator output terminals started with control through a field rheostat, the supply being obtained from DC Exciter.

A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The process is known as rectification, since it "straightens" the direction of current.
