You use a half-wave rectifier where the system design does not require a full-wave approach.
Half wave rectifier output is used for running ac motors.

How many diodes can be used in center tap type rectifiers?
There are two diodes in a standard center tapped configuration of a rectifier. This is per phase, so if you had a three phase system, each winding having a center tap, all of which are connected together, you would have six diodes.
What does a bridge rectifier do?
Imagine a rectifier as a valve that only allows electrical current to flow in one direction. When using a single rectifier you end up with half of the wave cycle being cut off (when the cycle turns negative). In many applications a full wave rectifier would be far more desirable. By configuring four of the rectifiers it is possible to make what's called a full wave "bridge". The link below shows how a full wave bridge works. http://hyperphysics.phy-astr.gsu.edu/Hbase/electronic/rectbr.html ANSWER: It will rectify the input into pulsating DC of twice the input frequency minus two diodes drop 1.4 volts
Why a full wave rectifier is preferred over a half wave rectifier?
The a.c. component, or ripple, produced by the 4-diode (full wave) bridge rectifier is the same as that produced by the 2-diode full wave rectifier. The bridge is connected across the secondary winding of a transformer. The 2 diodes of the other type of full wave rectifier are each connected to one end of a winding, but that winding requires a center tap. For any desired value of d.c. after rectification, the a.c. voltage of the 2-diode rectifier winding has to be twice that of the winding required for the bridge.
How many diodes will a high output alternator usually contain?
An alternator usually has 6 diodes in a full-wave rectifier for the main current output connected directly to the battery, and also another 3 for the secondary output to the voltage regulator, which feeds DC through slip-rings to the field coil in the rotor.
How many type of diode?
There are many types of diodes that are used for different functions in electronics. The most common types include the laser diodes and the light emitting diodes (LED).
How many diodes in a bridge rectifier?

How many diodes does a basic automotive alternator rectifier have?
Nine
Why use half wave rectification and what are its advantages over full wave rectification?
A full-wave rectifier will provide an output through both the positive and negative halves of the AC sine wave. The half-wave rectifier will only provide an output for half the cycle. The filtered outputs of both rectifiers can be "smoothed" well, but the higher the load on the half-wave rectifier, the more the output voltage will vary across a cycle of input power. This results in higher ripple and makes regulation a bit more difficult. The full-wave rectifier will provide an output through both the positive and negative halves of the sine wave. It effectively "inverts" the negative half of the cycle and provides two "pulses" of power per cycle as opposed to one pulse per cycle for the half-wave rectifier. The full-wave rectifier might use a pair of diodes and a center tapped transformer, or might use four diodes in a full wave bridge configuration and a transformer with no center tap.

Where did Light Emitting Diodes get made?
They make them in many different places.
What are examples of diodes?
There are so many different types of diodes. Some of the common examples include light emitting diodes, silicon diodes, zener diodes and so many more.
Types of rectifier?
There are basically two types of rectifiers one is the half wave rectifier and the other is the full wave rectifies. The full wave rectifier is further classified into two types namely the bridge rectifier and the center tapped rectifier.There are also silicon controlled rectifiers nowadays.
