Thyristors - SCRs - Modules is a classification of mainly used semiconductor components.
The VS-VSKT230-18PBF is among these components and presents several advantages: it is a vertical, insulated-type Thyristor Module with a trench gate structure, the need of gate voltage is low, it can easily be run with a gate signal of 4 V or less, it has lower power loss and higher temperature.

The VS-VSKT230-18PBF has high surge capability and reliable performance, which makes it ideal for applications demanding superior performance and cost efficiency. These include AC and DC motor control, uninterruptible power supply (UPS), wind turbine power converters, inverters, rectifiers, and power factor correction (PFC).

Working Principle

The working principle of the VS-VSKT230-18PBF Thyristor module is based on the switching of electrical signals. After the gate voltage is applied, the gate current flows to turn on the Mode leading SCR, which allows current to go through it and into the Mode trailing SCR. This in turn allows current to go through the SCR and out of the terminal, thus forming a closed loop.

When the gate current is removed, the Mode leading SCR is turned off and the Mode trailing SCR is turned on, largely reducing the output voltage. The SCR then blocks all current, the loop is opened, and the output voltage returns to normal conditions. This process is repeated in each cycle and allows for a fast switching of the module\'s output voltage.

Application Field

The VS-VSKT230-18PBF can be used in a number of applications, from power conversion to motor control and rectification. It is ideal as an AC and DC motor control, as it is low cost and efficient, and moreover, it can be applied for active front-end (AFE) and uninterruptible power supply (UPS) systems.

It is also useful in wind turbine power converters, where its low power loss can be especially useful. Additionally, the VS-VSKT230-18PBF is suitable for three-phase or single-phase rectifiers, which are used as a power electronics device for converting alternating current into direct current.

Moreover, the VS-VSKT230-18PBF can be used to boost the power factor of motor-driven loads, inverters, and rectifiers. This facilitates a better efficiency of operation and reduces energy losses due to the improved power factor of the system.

Conclusion

The VS-VSKT230-18PBF Thyristor Module is designed for use in a wide range of applications, from motor control and power conversion to inverters and rectifiers. Thanks to its low power loss, current surge capability and efficient performance, it gained popularity for being cost-effective and reliable.

Its low gate voltage requirement allows easy and fast switching, while the vertical insulated-type structure facilitates an efficient operation and improved power factor. The higher temperature and current ratings provide reliable performance in a wide range of situations and applications.
