Half Wave Rectifier

A half-wave rectifier is an electronic circuit, and a type of rectifier that rectifies only half cycle of the waveform. It gets its name from the fact that only half the sine wave of the alternating current passes through it and is converted to direct current. The half-wave rectifier consist a step down transformer, a diode connected to the transformer and a load resistance connected to the cathode end of the diode. 

The main supply voltage is given to the transformer which will increase or decrease the voltage and give to the diode. In most of the cases, the step-down transformer is used to decrease the supply voltage. This decreased alternating current voltage is given to the diode which is connected serial to the secondary winding of the transformer, diode is electronic component which will allow only the forward bias current and will not allow the reverse bias current.

Rectifier

Rectifier is an electronic device which converts the alternating current to unidirectional current, in other words rectifier converts the alternating current voltage to direct current voltage. The process is known as rectification. Physically, rectifiers take a number of forms, including vacuum tube diodes, mercury-arc valves, copper and selenium oxide rectifiers, semiconductor diodes, silicon-controlled rectifiers and other silicon-based semiconductor switches. You can find rectifier in almost all the electronic devices because rectifier can convert the main voltage into direct current voltage in most power supply part, and every electronic device will work on the direct current voltage supply only. Rectifiers are classified according to the period of conduction. They are half wave rectifier and full wave rectifier.
