What is the bridge?

The

bridge rectifier is an electronic component that produces direct current output (DC) from the AC input (AC). Components are commonly found in AC Converters used to power DC devices or batteries and functions by removing the constant conversion of the polarity that characterizes the AC power sources. This is achieved by directing incoming alternating power via a series of diodes that forces a constant, set positive/negative relationship in the output power. The diodes in the bridge rectifier can be free, individual units soldered on a circuit plate (PCB) or be integrated into a single compact component. Eight bridges can produce DC outputs from single -phase or three -phase alternating needs with configurations consisting of four and six diodes. This regular shift in polarity gives AC power supply to the power supply of its characteristic form of sinusoid wool. On the other handa positive or negative relationship. The bridge rectifier is one of the methods of smoothing the undesirable ripple polarity from the AC power supply for use in DC power sources. These devices use one -way current conductive characteristics of semiconductor diodes to force AC input to maintain a constant positive/negative output orientation.

This rectifier device works using diodes located in pairs, each with AC input point and shares common positive and negative DC points. When the AC power supply is applied to the bridge, each pair blocks or allows you to pass through. This corresponds to the shifts of the polarity of force, but ensures that the positive and negative peaks of each alternate stream are at the same point on the bridge. This creates a DC power output with a set polarity and smooth wool shape and minimal abolition of the alternating current. Any ripple remainingIt can then be further flattened by the insertion of extermination components, such as capacitors via the output.

bridge rectification can be presented in a series of form depending on a specific application. The application of heavy bridge rectifiers usually use individual diodes mounted on cooling sinks or soldered on PCB. For applications requiring lower current values, bridge rectifiers are usually supplied as compact individual components that have built -in diodes. These small square packages have four wires, two for AC input and two for positive and negative DC outputs. The positive position of the lead on the rectifiers of the packages is often identified by a diagonally cut corner on the body of the rectifier.
