A full-wave rectifier converts the whole of the input waveform to one of constant polarity (positive or negative) at its output. Mathematically, this corresponds to the absolute value function. Full-wave rectification converts both polarities of the input waveform to pulsating DC (direct current), and yields a higher average output voltage.
SCR 4-layer (p-n-p-n) diagram. A silicon controlled rectifier or semiconductor controlled rectifier is a four-layer solid-state current-controlling device.The name "silicon controlled rectifier" is General Electric's trade name for a type of thyristor.
In power supply design, a bridge circuit or bridge rectifier is an arrangement of diodes or similar devices used to rectify an electric current, i.e. to convert it from an unknown or alternating polarity to a direct current of known polarity. In some motor controllers, an H-bridge is used to control the direction the motor turns.

Pulsed DC is commonly produced from AC (alternating current) by a half-wave rectifier or a full-wave rectifier. Full wave rectified ac is more commonly known as Rectified AC . PDC has some characteristics of both alternating current (AC) and direct current (DC) waveforms.
Active full-wave rectification with two MOSFETs and a center tap transformer. Replacing a diode with an actively controlled switching element such as a MOSFET is the heart of active rectification. MOSFETs have a constant very low resistance when conducting, known as on-resistance (R DS(on)). They can be made with an on-resistance as low as 10 ...
For purposes of illustration, a basic full-wave diode-bridge rectifier is shown in the first stage, which converts the AC input voltage to a DC voltage. Operation
The device does not attain its full blocking capability until the reverse current ceases. Reverse biased: For a bias between breakdown and 0 V, the reverse current is very small and asymptotically approaches -I s. For a normal P–N rectifier diode, the reverse current through the device is in the micro-ampere (μA) range.
