Diodes - Rectifiers - Single - CRSH2-2 BK Application Field and Working Principle

Introduction

CRSH2-2 BK is a single diode rectifier which is designed to achieve full-wave rectification. It is a semiconductor device that enables current to flow in one directions while blocking the opposite direction. That is to say, CRSH2-2 BK rectifier can fully exploit AC source’s alternating current to direct current. CRSH2-2 BK has wide ranges of application fields such as power supply, light source power supplies, battery charging, industrial control rectifier and communication equipment rectifier. In this article, application field and working principle of CRSH2-2 BK will be illustrated.

Application Field of CRSH2-2 BK

CRSH2-2 BK can be applied to many industries. Firstly, in power supply filed, CRSH2-2 BK rectifiers are widely used as the most fundamental building blocks of many power systems. They are used to rectify AC power from the wall plug or from other sources to DC. Secondly, in light source power supplies, the diode rectifier is the most common method of obtaining filtered DC supply and is used to power the electronics in electronic fluorescent light sources. Thirdly, CRSH2-2 BK are used in battery charging, and can assist to rapidly charge rechargeable battery up to the peak capacity as quickly as possible. They are also widely used in industrial control rectifier and communication equipment rectifier like cell phone charger, computers and so on.

Working Principle of CRSH2-2 BK

CRSH2-2 BK is a single diode rectifier. A generic diode rectifier consists of two or more diode, the diode acting as a switch or gate to allow or exclude current flow in a circuit. When the polarity of the supply voltage is positive with respect to ground, current can flow through the rectifier. But if the voltage being applied is negative with respect to the ground, current is blocked and can not flow through the rectifier.This rectifier conducting direction will be flipped every half-cycle of the alternating current. The opposition line of contact of the voltage and current direction is called "reverse recovery time", during which the current in the diode decrease to zero. This is why the single diode rectifier can only achieve one-way rectification.

Conclusion

In conclusion, CRSH2-2 BK is a single diode rectifier with wide application range and simple working principle. It is used to transform AC power from wall plug or other sources to DC power, and has been widely used in power supply, light source power supplies, battery charging, industrial control rectifier and communication equipment rectifier.
