30.157

30.157 is a type of bridge rectifier, which is widely used in AC-DC conversion. Bridge rectifiers, commonly known as full wave rectifiers, are named so because of the bridge structure of the four rectifying tubes on the circuit board. Due to the unique features of bridge rectifier, it can obtain DC voltage or current from the AC power supply, and can convert the AC power supply into DC power supply without the need of transformers.

The working principle of the bridge rectifier is relatively simple. The rectifier circuit includes input terminals, a bridge rectifier composed of four rectifying tubes, and output terminals. Among them, the common anode and cathode are connected to the positive and negative outputs, and the other two electrodes are connected to the input terminals. When the AC power supply is connected to the input end, coil or iron core electromagnetic power needs to be used to enhance the intensity of the current. Under normal circumstances, the bridge rectifier will start to work without transformers or other components after the power is turned on.

In the circuit part, the two diodes of the bridge rectifier are reverse-biased, and the current is not allowed to pass through the two tubes. At this time, the current can only pass through the other two tubes. When the anode of the combined tube is negative, diode 1 is forward biased and diode 2 is in reverse bias. When the anode of the tube is positive, diode 3 is forward biased and diode 4 is in reverse bias.

In the process, the bridge rectifier charges and discharges alternately as the AC voltage changes. The voltage appears at the output end is no longer an AC, but a pulsed DC, but it will be continuous after filtering. When the peak current generated by the bridge rectifier is limited, the transmitted DC voltage eliminates the ripple waveform and can be stabilized.

30.157 Bridge Rectifier is used in all kinds of occasions. In particular, it is widely used in automotive switching power supply, computer power supply, adsl modem power, household appliances, LED driving power supply, UPS power supply, medical equipment, communication equipment, industrial equipment and other fields. More importantly, its safety, reliability, and energy saving performance can meet the needs of most applications.

From the above introduction, we can conclude that 30.157 Bridge Rectifier has many characteristics and wide application field, which makes it play an important role in the current power supply industry. Its admirable performance and long service life have made it a popular choice of many consumers.
