Thyristors are a type of semiconductor that utilizes the properties of a three-junction device to control the electric current passing through it. The most common type of thyristor is the DIAC, which stands for diode-controlled alternating current. The DIAC can be used as an AC switch, a relay, a gate, or a voltage regulator. DIACs are most commonly used in power supplies and motor starters, as well as for switching and time delay relays.

SIDACs, on the other hand, stands for static induction diode. Unlike DIACs, SIDACs are a static device and thus do not require any external DC power source. They are mainly used for triggering or blocking of current pulses. SIDACs are typically used in circuits where very fast switching times are required, such as motor controllers, frequency converters, pulse width modulator circuits, and ignition circuits.

The K1500G is a high power thyristor, based on the DIAC and SIDAC technology. It is primarily used in switching and power control applications. The K1500G employs three junctions and two gate terminals to control the flow of current.

The K1500G operates by controlling the voltage across the device by regulating the current passage through the gate. When a voltage is applied to the gate terminal, the current passing through the two junctions is increased and increased current is flowing through the third junction, thus regulating the flow of current. By changing the voltage applied to the gate terminal, the current passing through the device can be controlled, thus controlling the switching of the device.

The K1500G is used mainly in motor control, frequency conversion, and ignition systems. In motor control applications, the K1500G is used to regulate the current passing through the motor, thus increasing or decreasing the speed of the motor. In frequency conversion applications, the K1500G is used to switch the current between two different frequencies, thus controlling the output frequency. Lastly, in ignition systems, the K1500G is used to control the current through the spark plug, thus controlling the ignition timing.

The K1500G has many advantages over other thyristors. One of the main advantages is its high power capability, making it suitable for applications that require high current control. Additionally, the K1500G is highly reliable and can operate at temperatures up to 210°C. This makes it ideal for high temperature applications. The K1500G also has a fast response time, with switching times as fast as 20-50 us. This makes it suitable for applications where fast switching is needed.

In conclusion, the K1500G is a high power thyristor based on DIAC and SIDAC technology. It is mainly used in motor control, frequency conversion, and ignition systems due to its high power capability, high reliability, and fast response time.
