Thyristors are the most popular and commonly used switching devices in the modern power electronics industry. They offer fast, precise switching of AC and DC currents, and can be used for a wide variety of applications, from basic switching to complex and sophisticated control systems. A type of thyristor is the K2201G, which is a highly advanced thyristor used for controlling both AC and DC as well as regulating the required peak current in a circuit.

The K2201G, or three-quadrant TRIAC, is a type of thyristor characterized by its ability to switch AC currents in both directions. This type of thyristor is most often used in power electronics applications when a device is required to switch an AC current in both directions. The switching of switches can be in either direction, causing the current to switch direction at each cycle, and allowing it to be changed either forward or backward.

The K2201G is composed of three PN junctions in series with the central junction being the gate. The PN junctions are placed between the terminals of the device and the gate is connected to a control voltage. When a voltage is applied to the gate, a current called the “gate current” is created, which allows the device to switch quickly and accurately by changing the voltage across the gate. The switching of the device takes place when the voltage across the gate is changed, opening or closing the junction depending on the direction of the applied voltage. The switching of the device is compared to a relay in the sense that it responds quickly to the applied voltage and is designed to switch on or off at the required voltage.

DIACs and SIDACs are two other types of thyristors. DIACs are a type of thyristor used to control AC and DC currents, as well as to ensure the safe switching of a current. DIACs are two-quadrant thyristors and operate as two terminals connected to two diodes. When the voltage applied to the terminals is greater than the voltage of the diode, the diode is turned off, thereby preventing further current from flowing.

SIDACs are also two-quadrant thyristors, but operate differently than DIACs. SIDACs work on the same principle of using two terminals to control the current, but the terminals are not connected directly. Instead, the terminals are connected via a coil and the current can be controlled by adjusting the voltage across the coil. Unlike DIACs, SIDACs can be used to control both AC and DC currents.

K2201G thyristor is a three-quadrant thyristor, which means it is capable of controlling both AC and DC currents. It offers fast and accurate switching of the current, and is ideal for use in industrial and power electronics applications. It is also designed to respond quickly to a change in voltage across the gate, allowing it to be turned on or off at the desired peak current. DIACs and SIDACs are also two-quadrant thyristors, and are used in many applications, such as controlling AC or DC currents.
