Thyristor is short for thyristor, also known as thyristor rectifier, previously referred to as thyristor; In 1957, the American General Electric Company developed the world's first thyristor product and commercialized it in 1958. The thyristor is a PNPN four-layer semiconductor structure, which has three poles: anode, cathode and gate; Thyristors have the characteristics of silicon rectifier devices, and can work under high voltage and high current conditions, and its working process can be controlled, and it is widely used in controlled rectifier, AC voltage regulation, contactless electronic switch, inverter and frequency conversion electronic circuits.
The conduction conditions of thyristor are as follows: adding a forward voltage and triggering current at the gate; The derived devices include fast thyristor, bidirectional thyristor, reverse-guided thyristor, optically controlled thyristor, etc. It is a high-power switching type semiconductor device, which is represented by the text symbol "V" and "VT" in the circuit (the old standard is represented by the letter "SCR").
Thyristor (Thyristor) is a kind of switching element, which can work under high voltage and high current conditions, and its working process can be controlled, and is widely used in controlled rectification, AC voltage regulation, contactless electronic switch, inverter and frequency conversion and other electronic circuits, is a typical small current control high current equipment. In 1957, the American General Electric Company developed the world's first thyristor product and commercialized it in 1958.
