Single-phase half-wave rectifiers pass voltage across a single diode. In this circuit, only the positive half of the AC input voltage transmits to the output across the load resistor. If the diode is reversed, only the negative half of the AC input voltage would appear across the resistor.

Single-phase diode rectifiers, converting AC signal into a DC voltage, exist in two types – half-wave and full-wave. Half-wave diode rectifier was mentioned before. Full-wave diode rectifiers can be of two types as well – with a center-tapped transformer and bridge rectifier.

A rectifier is an electronic device that converts an alternating current into a direct current by using one or more P-N junction diodes. A diode behaves as a one-way valve that allows current to flow in a single direction. This process is known as rectification.

It is defined as the angle measured from the instant that gives. maximum output voltage to the one at which it is actually triggered. It is measured from the angle that gives the largest average. output voltage.

Silicon Controlled Rectifier (SCR) may be used as a controlled half wave rectifier, unlike normal half wave rectifier. The AC voltage to be rectified is applied to the input of the power transformer.
