Thyristors are a type of semiconductor device in which a small electric current can control a larger one. SCRs, or Silicon Controlled Rectifiers, are a type of thyristor that has a JEFT structure, meaning the anode is connected to the gate, the two junctions form the equivalent of a p-i-n diode, and the gate requires a positive voltage to trigger the gate of the device. The SCR modules are three-terminal devices consisting of an SCR and a heat sink, which improve the overall performance of an SCR as well as providing greater energy savings.

The SCR module VSKU91/10, made by Changchun Wan Qiang Technology Co, is an Aluminium material high voltage module with an SCR as the main component and a heat sink for better heat dissipation. It adopts high input impedance, high performance and reliable devices, with an excellent performance such as low conduction loss, high surge capability, and high switching speed. It also has a wide working temperature range from -40°C to + 120°C. The input current is up to 60A, and the maximum peak off-state voltage up to 800V DC.

The VSKU91/10 can be used in a wide range of applications such as motor control systems, and frequency conversion control modules, as well as being used in electric switchgear, frequency and AC power control systems. It is also used in telecom and broadcast systems, high-speed EDM machine, lighting control systems, railway systems, solar energy systems, high power motor drive system and low-frequency power supply. In addition, it can also apply in other industries such as automotive, aerospace, military, etc.

The working principle of the VSKU91/10 is simple. When a positive voltage is applied to the gate, the current is conducted directly through the SCR and to the load, and the SCR behaves like a perfect diode. The positive voltage applied to the gate keeps the SCR in the on position, and when the voltage is removed, it can switch to the off position. This makes the VSKU91/10 ideal for controlling current flow in a wide range of applications, from motor control to switchgear.

The VSKU91/10 provides excellent performance in both static and dynamic operations. It has low conduction losses and can switch current efficiently at high speed. In addition, it can also withstand large repetitive power surges and withstand high-frequency transients without any damage. This makes it ideal for high-power applications such as motor drives, AC power control systems, solar energy systems and railway systems.

Overall, the VSKU91/10 provides excellent performance and reliability, making it an ideal choice for a wide range of applications requiring efficient power switching. Its wide working temperature range and high capacity makes it suitable for a variety of different applications, including motor control systems, frequency conversion control modules, electric switchgear, lighting control systems, telecom and broadcast systems, frequency and AC power control systems, high-speed EDM machines, solar energy systems, railway systems, high power motor drive systems, and low-frequency power supplies. In addition, its excellent performance with high input impedance, high surge capability, and fast switching speed makes it suitable for use in a variety of different applications.
