Thyristors (also commonly referred to as silicon controlled rectifiers) are two-terminal solid state devices that can be used for a variety of purposes. The TVB025RSC-L thyristor family is a special type of thyristor, specifically designed to switch power in AC and DC applications. This article will explain the application field and working principle of the TVB025RSC-L family.

The TVB025RSC-L family is designed for a wide range of applications. These thyristors are capable of providing reliable switching of power in most AC and DC power supply systems. In addition, they can be used in many DC and AC motor control applications such as speed control, torque control and reversing. They can also be used as phase angle controllers for controlling the frequency and voltage of an AC waveform. These applications can generally benefit from the use of the TVB025RSC-L family due to its strong performance in both AC and DC switching.

In addition to the various applications that can be performed with the TVB025RSC-L thyristors, they are also ideal for high-power applications. The TVB025RSC-L has a blocking voltage range of up to 800V, and can handle up to 20A of current. This makes it suitable for both high-voltage and high-current applications. The thyristor also boasts a high rated dielectric strength, allowing for higher surge currents to be handled without damaging the device.

To understand how the TVB025RSC-L thyristor works, it is important to understand the principle of thyristor switching. The basic principle is based off of the diode rectifier bridge. The circuit uses a combination of conventional diode and a thyristor device, where the thyristor acts as a switch. The current can only flow through the thyristor when it is in a “forward-blocking” state, meaning that the voltage must be applied to the anode of the thyristor before it will start to conduct. When the voltage across the device is removed, the thyristor returns to a “reverse-blocking” state, meaning that current will no longer flow.

Once the device is in the forward-blocking state, any increase of the voltage across the anode will cause the thyristor to become more conductive. As the voltage increases, the current through the thyristor will also increase, allowing the device to handle larger currents. The thyristor can remain conductive until the voltage across it decreases to a certain value, at which point the device switches off and returns to its reverse-blocking state.

The TVB025RSC-L thyristor family is ideal for a wide range of applications, providing reliable switching power for many AC and DC applications. Furthermore, due to its current capacity and high-voltage rating, it is suitable for use in high-power applications as well. The working principle of the TVB025RSC-L thyristor relies on the combination of a diode rectifier bridge and the thyristor, where the thyristor acts as a switch.
