Answer: The primary function of a thyristor is to control electric power and current by acting as a switch. For such a small and lightweight component, it offers adequate protection to circuits with large voltages and currents (up to 6000 V, 4500 A).
Answer: Thyristor Tutorial. In many ways the Silicon Controlled Rectifier, SCR or just Thyristor as it is more commonly known, is similar in construction to the transistor. ... In fact the circuit symbol for the thyristor suggests that this device acts like a controlled rectifying diode.
Answer: Thyristors are mainly used where high currents and voltages are involved, and are often used to control alternating currents, where the change of polarity of the current causes the device to switch off automatically, referred to as "zero cross" operation.
Answer: Thyristor is a four semiconductor layers or three PN junctions device. It is also known as \u201cSCR\u201d (Silicon Control Rectifier). The term \u201cThyristor\u201d is dervid from the words of thyratron (a gas fluid tube which work as SCR) and Transistor. Thyristors are also known as PN PN Devices.
