Introduction to Thyristors - SCRs

Thyristors - SCRs are semiconductor devices consisting of four layers of alternating P and N type materials, connected in a series which can be triggered into conduction and block the current flow following a positive bias applied to the gate terminal. Depending on the type of thyristor, they can be triggered with a voltage, a current, or a combination of both. Thyristors are among the most popular switching devices and are used in a wide range of applications, from controlling and regulating power supplies to various high-precision measurement systems such as those used for industrial process control.

Applications of the VS-ST1200C20K0P

The VS-ST1200C20K0P is a 1200V Thyristor-SCR with a steady-state current rating of 20kA. It is a special-purpose device with a variety of uses, from industrial and commercial power switching and control to large-scale high-voltage power transmission, regulation and protection.Its high-voltage and high-current capabilities make it suitable for a number of applications. It can be used in repetitive DC and AC controllers, high-power motor control systems, power generation systems, power supply systems and arc furnace rectifier systems.

Working Principle of the VS-ST1200C20K0P

SCRs are devices consisting of an anode, a cathode and a gate, which are connected in series. When a voltage higher than the device\'s forward breakover voltage is applied to the anode terminal, the device starts to conduct current, and the voltage at the cathode will drop to a certain level. The gate terminal needs no additional voltage, but it can be biased to adjust the current flow, which is usually done by a gate drive circuit. Current flow then continues until the voltage across the device falls below its reverse breakdown voltage.To restart the device, the current must be shut off first and the circuit re-energized, either manually or by a control circuit. This makes the VS-ST1200C20K0P ideal for applications that require highly precise control over current and voltage.
