Thyristors - SCRsThe TS820-600T is a silicon control rectifier (SCR) or thyristor device with a current rating of 600A and a blocking voltage rating of 800V. It is commonly used in power control applications, especially in industrial and traction motor controls.A thyristor is a semiconductor device which is triggered in an alternating current (AC) circuit to control the current flow. It acts as a switch to turn on (or off) the AC power supply when triggered. The device works by controlling the voltage drop across an electrical device. It is most often used to regulate the power supply in critical applications, from small industrial tools to large tractors or turbines.The operation of the TS820-600T SCR can be explained in terms of the principles of its four main components. A gate connects the anode and cathode of the SCR and is used to start and control the current. A diode is connected between the anode and cathode of the device and has the function of allowing the current to flow in one direction only. The junction field effect transistor (JFET) and the resistor are used to control the gate current and speed at which the current flows through the device respectively.The TS820-600T SCR is a preferred choice in controlling the AC current in induction motor applications due to its high power switching capability, fast response time and high efficiency. Its motor control applications include motor speed control, motor starting, soft start, motor braking and AC arc flash prevention in motor controllers.The device can also be used in AC firing circuit applications such as emergency DC power supplies and uninterruptible power supplies (UPS). In this application, the SCR is used to regulate the current flow in the circuit, ensuring that no spikes or surges occur. Additionally, it can be used to regulate the voltage in circuits with capacitors and inductors which tend to elevate and reduce the voltage, respectively.The TS820-600T SCR is also highly suited for power factor correction in induction motor applications, as well as for medium voltage (up to 800V) AC power electronic applications. As such, it is a preferred choice for power distribution and transmission applications.The SCR works on the principle of using a thyristor or semiconductor switch to trigger an AC current into the electrical device being controlled. The device is triggered by a small voltage or current applied to its gate which, in turn, starts a gating current which then turns on the main current flow through the SCR conducting channels. The thyristor remains in its conducting state until the current is stopped and can be used to efficiently regulate current, voltage and power in AC circuits.In summary, the TS820-600T SCR is a robust and reliable thyristor with a current rating of 600A and a blocking voltage rating of 800V. It is commonly used in power distribution and transmission applications and in industrial and traction motor control. With its high power switching capability, fast response time and high efficiency, the device is a preferred choice in controlling the AC current in induction motor applications. Additionally, it can also be used in an AC firing circuit to regulate the current flow and control the voltage.
