Introduction to UGB18CCTHE3/81

The UGB18CCTHE3/81 is a three-phase bridge rectifier manufactured by the Infineon Technologies Corporation. It is part of their UGB Series of rectifiers and can be used to provide a direct current (DC) source of power in home, industrial, and automotive applications. The UGB Series rectifiers offer excellent reliability, great efficiency and a cost-effective solution for a variety of applications.

Applications of UGB18CCTHE3/81

The UGB18CCTHE3/81 is a three-phase bridge rectifier designed for direct current (DC) power distribution applications. The rectifier is best suited for use in single and multiphase AC-DC power supplies as well as uninterruptible power supplies (UPS). This type of rectifier can also be used in variable frequency drives (VFDs), home electrical power distribution, and automotive applications.

Features

The UGB18CCTHE3/81 rectifier has a maximum continuous current rating of 18A, a peak surge current rating of 35A, and a maximum DC output voltage of 800V. The device has a wide operating temperature range of -40 to 125 °C and is designed to withstand a 10 ms surge at 85A as well as a 20 µs surge of 100A. The UGB18CCTHE3/81 rectifier offers excellent efficiency, with a typical efficiency of 94.5% at full load. The UGB18CCTHE3/81 rectifier has built-in overcurrent protection, undervoltage lockout (UVL), and reverse polarity protection features. It also features built-in thermal shutdown, which protects the device in case of excessive heat. The UGB18CCTHE3/81 utilizes a dynamic or static bypass feature, which allows the user to maximize efficiency while avoiding excessive heat generation.The UGB18CCTHE3/81 rectifier is available in a TO-220 package that can be mounted either horizontally or vertically on a standard PCB with a minimum space requirement. The package is constructed with a two-piece mold that prevents solder from entering the package.

Working Principle

The UGB18CCTHE3/81 rectifier operates using the principle of a three-phase full-wave bridge rectifier. When operating in a three-phase power supply, the device will use the three phases of the incoming AC power to charge the three diodes in the rectifier circuit.When the voltage at the input of the rectifier reaches zero, all three diodes in the circuit become forward biased and the device begins to conduct. During this period, the device will effectively transfer power from the phase voltage to the load.As the voltage at the input of the rectifier begins to increase, the diodes stop conducting and the device reverts to an off state. This cycle continues, with the UGB18CCTHE3/81 rectifier effectively transferring power from the AC power source to the load in a controlled and efficient manner.

Conclusion

The UGB18CCTHE3/81 rectifier is a three-phase bridge rectifier manufactured by the Infineon Technologies Corporation. It is part of the UGB Series of rectifiers and is ideal for single and multiphase AC-DC power supplies, uninterruptible power supplies, variable frequency drives, and home electrical power distribution applications.The device has a maximum continuous current rating of 18A, a peak surge current rating of 35A, and a maximum DC output voltage up to 800V. Additionally, it features a dynamic or static bypass feature for efficiency, built-in overcurrent protection, undervoltage lockout, reverse polarity protection, and thermal shutdown protection. It also has a wide operating temperature range of -40 to 125 °C.The UGB18CCTHE3/81 rectifier utilizes the principle of three-phase full-wave bridge rectification to supply direct current power to its load with excellent efficiency while avoiding excessive heat generation.
