The process through which the alternating voltage waveform (AC voltage) of the electrical power is converted into a direct (constant) voltage waveform (DC voltage) or into a pulsating waveform with a direct (DC) component is called rectification. The electronic equipment that makes this conversion in a static process is called rectifier.
An example of a fully-controlled 3-phase bridge rectifier is given below: We have seen in this tutorial that three-phase rectification is the process of converting a 3-phase AC supply into a pulsating DC voltage as rectification converts the input power supply of a sinusoidal voltage and frequency into a fixed voltage DC power.
The full wave rectifier converts both halves of each waveform cycle into pulsating DC signal using four rectification diodes. In the previous power diodes tutorial we discussed ways of reducing the ripple or voltage variations on a direct DC voltage by connecting smoothing capacitors across the load resistance.
Thus, the rectifier makes a DC/AC conversion, operating in inverter mode. This steady state can be obtained in the 2nd quadrant when the current direction is reversed (Id < 0) or in the 4th quadrant when the Vd voltage polarity changes (Vd < 0).
