Thyristors - SCRs: TS1220-600H Application Field and Working Principle

Thyristors, specifically Silicon Controlled Rectifiers (SCR), are a type of semiconductor device. Developed in the late 1950s, SCRs were heralded as the dawning of a new era in the electronics industry and were used to control and switch high power, as an alternative to complex mechanical solutions.The TS1220-600H is a Pulse/Phase Controlled SCR, designed to be used in applications such as AC motor controllers and industrial controls. It features a 600V rating and a maximum Let-Through Voltage (LTV) of forward blocking voltage of 1200V. This makes it suitable for industrial applications, including those involving high-level AC power.The TS1220-600H is a three-terminal device, with the main terminals referred to as anode (A), cathode (K), and gate (G). When no voltage is applied to the gate terminal, the anode-cathode junction is in a reverse-blocking state, where electricity can\'t flow between the two main terminals. When a pulse of current is supplied to the gate terminal, this junction switches to a forward-conduction state, which allows current to flow.The TS1220-600H is typically used in motor control applications, as it is able to switch high power and withstand high levels of current. The device allows control of the speed, direction, and torque of the motor by controlling the phase angle between the inverter and motor circuits. It makes use of a Phase Angle Control Regulation System, which is used to accurately regulate the power input to the motor.The TS1220-600H works on the principle of phase angle control, where the angle is based on the duration of the pulse in the firing circuit. The pulse rate and pulse width can be precisely adjusted to produce the desired effect. The pulse is generated by an SCR Switching Pulse Unit (SPU) and fed to the gate terminal of the SCR. The pulse width determines when conduction begins in the SCR and the Pulse Repetition Frequency (PRF) determines the frequency in which the conduction continues.By controlling the PRF and pulse width of this device, the desired current can be maintained within the motor and the speed or torque adjusted accordingly. This type of control is known as Pulse Width Modulation (PWM) and is a key feature of the TS1220-600H SCR.The TS1220-600H is an extremely versatile device and can be used in a variety of applications. It can be used in rectifier circuits, motor speed control, HVAC systems, solar inverters, and various industrial control systems. It is also used in many medical devices and appliances, such as patient monitoring systems, wheelchairs, pumps, and ventilators.In conclusion, the TS1220-600H is a powerful and reliable SCR specifically designed for industrial applications. It operates on the principle of phase angle control, making it suitable for motor speed control. It has a high voltage rating, making it suitable for many HVAC and industrial control applications. The device is highly reliable and is used in a variety of applications, from medical devices to solar inverters.
