RD16A20-31-P6

RD16A20-31-P6 is a general communication high-voltage thyristor produced by Weihai Riyida Electronic Co., Ltd. It can control, regulate and adjust the direction, power, speed and other parameters of the load (generator). It has many uses, one of which is its application in the field of electric power. In this article, the application field and working principle of RD16A20-31-P6 will be discussed.The RD16A20-31-P6 is mainly used for the on-off or speed regulating control of AC motors, rectifier,power converter, generator sets and other loads in an electric power system. It can control the startup, stop, direction, stall and overload protection of an AC motor, rectifier, converter, generator set and other load.The working principle of RD16A20-31-P6 is simple. It consists of an SCR (Thyristor), a diode and a resistor. The SCR is a three-terminal semiconductor device and functions as a switch. To turn on an SCR, a control signal is applied to its gate. Default signal current is needed, while the voltage of the gate control power is usually less than 10V. The control signals are generated by the system micro-controllers or other electronic components.When the SCR is turned on, due to the gate control signal, the resistance between the main and the gating electrodes of the SCR drops and the main current begins to flow. Since the diode is connected in parallel with the SCR, the current is shared between them. The diode will try to maintain a constant voltage across the whole system. This ensures that the current in the load never exceeds the rated current.The resistor is also connected in parallel with the SCR. It is used to limit the current in the circuit when the SCR is turned on. The current may rise so high that it could cause electrical shock to humans or the system components. The resistor is usually set to a value that is slightly lower than the minimum triggering current value of the SCR so that the current is not too high to cause any hazard.In conclusion, RD16A20-31-P6 is a general communication high-voltage thyristor with many uses, one of which is its application in the field of electric power. Its working principle is based on the use of an SCR, a diode and a resistor. The SCR is used as a switch, the diode is used to regulate the voltage across the system and the resistor is used to limit the current. By using RD16A20-31-P6, the on-off or speed regulating control of AC motors, rectifier, power converters, and generator sets can be achieved effectively.
