A half wave rectifier is a circuit which converts one half of the alternating input voltage into direct voltage. This is achieved by using a junction diode in series with a load. During the positive cycle of the input alternating voltage, the diode is forward biased and conducts current.

Such rectifier circuit, as shown in Fig(a). is called a half-wave rectifier. The secondary of a transformer supplies the desired ac voltage across terminals A and B. When the voltage at A is positive, the diode is forward biased and it conducts.

Rectifier: A circuit or device that is used to convert an alternating voltage to a direct voltage is called rectifier. Action of semiconductor diode as a full wave rectifier: Electric circuit: The alternating voltage to be rectified is applied across primary coil (P 1 P 2) of a transformer with a centre tapped secondary coil (S 1 S 2).

Half Wave Rectifier is simple a single p-n junction diode connected in series to the load resistor. We know that a junction diode conducts current only in one direction. In other words, a p-n junction diode conducts current only when it is forward biased. The same principle is used to make a half wave rectifier to convert AC to DC.

A circuit or device that is used to convert an alternating voltage (or current) into direct (unidirectional) voltage (or current) is called a rectifier.

The scale of a full wave rectifier type average sensing meter is calibrated to read the r.m.s value for ideal sine wave signal (form factor 1.11). Determine the multiplying factor of the meter if it is used to measure the r.m.s value of square waves.
