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.
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.
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 characteristics and components of ripple depend on its source: there is single-phase half- and full-wave rectification, and three-phase half- and full-wave rectification. Rectification can be controlled (uses Silicon Controlled Rectifiers (SCRs)) or uncontrolled (uses diodes). There is in addition, active rectification which uses transistors.
Connecting an input and output terminal is not allowable with normal bridge topology, so Twin-T is used where a bridge would otherwise be used for balance or null measurement applications. The topology is also used in the twin-T oscillator as a sine-wave generator. The lower part of figure 1.11 shows twin-T topology redrawn to emphasise the ...
For 240 V operation, the switch configures the system as a full-wave bridge, re-connecting the capacitor center-tap wire to the open AC terminal of a bridge rectifier system. This allows 120 or 240 V operation with the addition of a simple SPDT switch. A voltage tripler is a three-stage voltage multiplier.
The current drawn by a motor or other electrical machine at its full rated power and standard voltage. full-wave rectifier A rectifier circuit that converts both positive and negative parts of the input alternating current waveform into a unidirectional, direct current. fuse
Three-phase full-wave (Graetz) bridge rectifier circuit using thyristors as the switching elements: Commutation process explained. When just valves 1 and 2 are conducting, the DC voltage is formed from two of the three phase voltages. During the overlap period the DC voltage is formed from all three phase voltages.
