CN647 BK

Diodes - Rectifiers - Single are devices that are used for rectifying electrical power from an alternating current (AC) power supply to direct current (DC) power supply. One of the most commonly used types of Single Rectifiers is the CN647BK. This article will discuss the application field and working principle of this device.

Application Field & Working Principle of CN647BK Rectifiers

The CN647BK Single Rectifier is a general-purpose, three-phase bridge rectifier. It can be used in motor control applications where a fast, efficient and inexpensive rectification is required. It is designed to rectify AC input voltage up to 320 volts into an output voltage of DC 130 volts. As it is a three-phase device, three inputs are required to produce one output voltage.

This device has the capability to deliver high current with little to no power dissipation, making it an ideal choice for many applications. Additionally, the device incorporates Safe Operating Area (SOA) and thermal protection features for increased safety and reliability.

The CN647BK is primarily used in motor control and other high-current applications. In motor control applications, the rectifier is used to convert the AC input into DC power, enabling the motor to run more efficiently while delivering smoother and quiet operation. Other uses for the CN647BK include industrial automation, LED lighting, battery chargers, and more.

The basic working principle of the CN647BK Single Rectifier is that of rectifying an AC voltage input to a DC voltage output. This is achieved through the use of a bridge rectifier consisting of four diodes that together form a full-wave rectifier. The AC input is fed into the bridge rectifier through two of the diode pairs and is then converted into a DC output voltage. The AC input voltage is also reduced to a safe level to ensure no harm is brought to the equipment.

Other features of this device include low reverse recovery time and low forward voltage drop, which helps to maximize efficiency. Additionally, the CN647BK has a soft recovery feature which helps minimize interference in motor control and other sensitive applications. It also has a wide operating temperature range of -40 to 125 ˚C, making it a great choice for high temperature applications. The device is also RoHS compliant and comes in TO-220AB and TO-220FP packages to suit a variety of different applications.

Conclusion

The CN647BK Single Rectifier is a general-purpose, three-phase bridge rectifier, primarily used for motor control applications. It has the capability to deliver high current with little to no power dissipation, making it ideal for many applications. Additionally, the device has a soft-recovery feature, a wide operating temperature range, and is RoHS compliant. While this article has focused on the application field and working principle of the CN647BK, it should be noted that more information is available from the manufacturer.
