A rectifier is a device that converts alternating current (AC) to direct current (DC). It is done by using a diode or a group of diodes. Half wave rectifiers use one diode, while a full wave rectifier uses multiple diodes. The working of a half wave rectifier takes advantage of the fact that diodes only allow current to flow in one direction.
In a half-wave rectifier, a p-n junction diode is used as a rectifier. It has a relatively simple circuit consisting of a p-n junction diode connected in series to a load. Given below is the Circuit diagram of the Half Wave Rectifier. The components of the Half Wave Rectifier are P-N Junction diode, Ac supply and the load.
Keywords: Rectifier, Half-wave rectification, Rectifier output smoothing. A widely used application of this feature and diodes in general is in the conversion of an alternating voltage ( AC ) into a continuous voltage ( DC ). In other words, Rectification.
You can see that the input of three-phase AC is like that of three single-phases separated by an equal time gap. So when we place a half-wave rectifier in each phase wire, the half-wave rectifier allows it to pass the positive half cycle and prevents the flowing of current in the negative half cycle. Thus it can convert AC to DC.
Rectifier efficiency (η) is the ratio between the output DC power and the input AC power. The formula for the efficiency is equal to: The efficiency of a half wave rectifier is equal to 40.6% (i.e. η max = 40.6%) To derive the RMS value of half wave rectifier, we need to calculate the current across the load.
In summary, the output characteristics of a half-wave rectifier exhibit a pulsating DC waveform with a voltage that rises and falls during the positive half-cycles of the input voltage. The output current flows through the load resistor only during these positive half-cycles.

What is a Rectifier?
Half-wave rectifiers. In the half-wave rectifiers, only half of the AC is allowed to pass through a diode while the other half is blocked. This is the simplest type of rectifier circuit because it uses one diode, but it is not very efficient because only one-half of the AC is converted to DC. Half-wave rectifiers are normally used in AC motors.
