Thyristor is an electronic component that finds extensive use in power electronics. It is a semiconductor device that can be used to control the flow of electricity in a circuit. Some synonyms for thyristor include silicon-controlled rectifiers (SCRs), Triacs, and Diacs. They are all electronic devices that can control the flow of electricity in a circuit. Some other synonyms for thyristor include gate turn-off thyristors (GTOs) and insulated-gate bipolar transistors (IGBTs). They are both used for high-power applications, and their function is to control the flow of electricity in electronic devices. In conclusion, the term thyristor is often used interchangeably with several other names in the field of electronics, its various alternatives are developed for many specialized purposes.
