P1803UBLTP Application Field and Working Principle

TVS (Thyristor) is a type of semiconductor device which is widely used in technology and industry. The P1803UBLTP electric registration and annularly decompressing thyristor, also known as TVS, is one of the most popular products in the TVS series. It is widely used in power supply, communication, instrumentation, automobile, SRS, motor drive, AC & DC electric box and other fields.

Application Field

The P1803UBLTP is a motorized register and ring-down thyristor capable of regulating the voltage and current in power and voltage systems. It is typically used in the fields of power supply, automobile, SRS, motor drive, AC & DC electric box, instrumentation and communication. It is commonly used in such applications as control system protection, motor drive protection, over-voltage protection, AC & DC electric box overvoltage protection, and overvoltage alarm system.

In power supplies, the P1803UBLTP thyristor can be used to control the output voltage and current, thus improving the power factor and boosting the efficiency of the entire system by increasing the control power and reducing harmonic distortion. In the motor drive field, the P1803UBLTP can be used to improve the speed regulation, and in the AC & DC electric box, it is often used for protection against overvoltage, overload protection and overvoltage alarm.

In communication, the P1803UBLTP can be used to protect communication lines and communication equipment from being damaged due to strong electromagnetic interference. In SRS and instrumentation, the thyristor can be used to protect the system from overvoltage and ensure the accuracy of the entire system.

Working Principle

The P1803UBLTP thyristors work on the principle of an electric current flowing through a thyristor that causes a voltage gradient across its two main terminals. The two terminals of the thyristor are the anode and the cathode. When the current flowing through the anode is greater than the current passing through the cathode, the voltage will increase, thus actuating the thyristor.

When the voltage on the anode is greater than the voltage on the cathode, the thyristor will switch into a low-voltage operation mode, meaning that the current through it will be reduced to a minimum. This mode will be maintained until the thyristor reaches a sense limit, at which point it will automatically switch into a high-voltage operation mode.

In high-voltage operation, the P1803UBLTP thyristor will continuously draw the current that it needs to operate and will continue to do so until the voltage drops below the set limit. When the voltage drops below the set limit, the thyristor will switch into a low-voltage operation mode again.

In conclusion, the P1803UBLTP thyristor is a highly reliable semiconductor device with wide application in many industrial and technological fields, and its electric registration and annularly decompressing thyristor can accurately and effectively control the voltage and current.
