Thyristor-Controlled Reactor (TCR) module, T221N18BOFXPSA1, is a turn-off controllable current regulator that is mainly used to control the current in an AC system. It is comprised of an auto switch that responds to an external control signal to activate a thyristor-controlled switched inductor device which regulates the current in the system. It can be used in a variety of applications such as motor system speed control, soft-start, adjustable power supply and harmonic filtering.

The TCR module consists of a power control section, a thyristor voltage control circuit, a DC voltage supply and a control system. The power control section consists of two sets of thyristors and a switchable inductor. The thyristor voltage control circuit is responsible for triggering the two thyristors to guarantee that the current in the AC system remains stable. The DC voltage supply provides voltage for the TCR module to control the thyristor impulse width.

The working principle of the TCR module involves controlling the voltage across the thyristor by adjusting its on-state and off-state times. This is done by varying the current through the thyristor. When the current through the thyristor increases, the voltage across it will be increased, thus reducing its switching time. When the current through the thyristor decreases, the voltage across it decreases as well, thus increasing its switching time.

In motor speed control, the TCR module is used to control the current so that the motor speed can be adjusted. By controlling the current, the speed of the motor can be increased or decreased. In soft-start applications, the TCR module is used to reduce the inrush current that occurs when the motor is started. This reduces the stress on the motor and ensures that it starts smoothly.

For adjustable power supply applications, the TCR module is used to control the voltage across a set of contacts to ensure that the output voltage is regulated. This helps to improve the power quality of the power supply and ensure that the output voltage remains constant. In harmonic filtering applications, the TCR module is used to filter out harmonics that are generated by electronic equipment and reduce power losses.

As a result, the TCR module, T221N18BOFXPSA1, is a versatile device that is used to control and regulate the current, voltage and harmonic content in AC systems. It can be used in a wide range of applications, such as motor control, soft-start, adjustable power supplies and harmonic filtering. It is an essential component in any power system that requires efficient and flexible control of the current and voltage.
