IRKT26/12A is a kind of Thyristors - SCRs - Modules and it has many great application fields and working principle. This article will discuss the application field and working principle of IRKT26/12A.

First of all, the application field of IRKT26/12A includes industrial power controlling, household electrical appliance controlling, phase control, speed and torque control in motor, soft starter, function generator, phase trigger and dynamic braking, etc. Specifically, it is used to convert low voltage DC signal into high voltage AC signal. With these application fields, IRKT26/12A can be used in industrial equipment, electrical appliances and consumer equipment such as air conditioners, fans, washing machines, microwave ovens, and other appliances. Furthermore, IRKT26/12A is also widely used in consumer electronics, medical equipment and security systems.

The working principle of IRKT26/12A is based on the function of thyristors. A thyristor is a four-layer semiconductor device, composed of two P-type and two N-type layers. The P-type layers are called an anode and the N-type layers are called a cathode. The anode is connected to the positive terminal of the direct-current power supply, and the cathode is connected to the negative terminal of the direct-current power supply. When a current flows through the anode to the cathode, the device conducts and becomes polarized, allowing the current to flow from the cathode to the anode. When the current stops flowing, the device turns off and prevents any further current from flowing.

In a IRKT26/12A module, there are two main parts, the main thyristor (T1) and the prepolarised thyristor (T2). The main thyristor T1 will be turned on when the applied voltage across the anode and cathode reaches the holding current. This current must be bigger than the nominal current of the thyristor. The holding current of the main thyristor can be adjusted by controlling the current of the prepolarised thyristor (T2). Make sure that the anode of the pre-polarised thyristor is connected to the gate of the main thyristor T1. By controlling the current of the pre-polarised thyristor T2, the current of the main thyristor T1 is adjusted, which allows the IRKT26/12A module to be used to control the voltage and current of the output load.

In summary, IRKT26/12A is a kind of Thyristors - SCRs - Modules and it has many great application fields and working principle. It is used to convert low voltage DC signal into high voltage AC signal and is widely used in industrial equipment, electrical appliances and consumer equipment. The working principle of IRKT26/12A is based on the function of thyristors. There are two main parts, the main thyristor (T1) and the prepolarised thyristor (T2). The current of the main thyristor T1 is adjusted by controlling the current of the pre-polarised thyristor T2.
