Definition - What does Rectifier mean? A rectifier is an electrical device composed of one or more diodes that converts alternating current (AC) to direct current (DC). A diode is like a one-way valve that allows an electrical current to flow in only one direction. This process is called rectification. A rectifier can take the shape of several different physical forms such as solid-state diodes, vacuum tube diodes, mercury arc valves, silicon-controlled rectifiers and various other silicon-based semiconductor switches. Rectifiers are used in various devices, including: DC power supplies Radio signals or detectors A source of power instead of generating current High-voltage direct current power transmission systems Several household appliances use power rectifiers to create power, like notebooks or laptops, video game systems and television. A rectifier is an electrical device that converts AC to DC. AC regularly reverses direction, while DC flows in one direction only. ...
Clipper and Clamper are widely used in analog television receivers and FM transmitters. The variable frequency interference can be removed by using the clamping method in television receivers, and in FM transmitters , the noise peaks are limited to a specific value, above which the excessive peaks can be removed by using the clipping method. Clipper and Clamper Circuit An electronic device that is used to evade the output of a circuit to go beyond the preset value (voltage level) without varying the remaining part of the input waveform is called as Clipper circuit. An electronic circuit that is used to alter the positive peak or negative peak of the input signal to a definite value by shifting the entire signal up or down to obtain the output signal peaks at desired level is called as Clamper circuit. There are different types of clipper and clamper circuits as discussed below. Working of Clipper Circuit The clipper c...
