Thyristor - definition of thyristor by The Free Dictionary

NettetThere are different techniques to control speed of AC motor. One of the very popular of them is by applying chopped AC waveform – means changing phase angle of applied AC waveform. This method is used in many different devices likeThe firing angle of a thyristor like TRIAC - that gives supply to motor, is delayed to decrease the motor speed or it is … The first thyristor devices were released commercially in 1956. Because thyristors can control a relatively large amount of power and voltage with a small device, they find wide application in control of electric power, ranging from light dimmers and electric motor speed control to high-voltage direct-current power … Se mer A thyristor is a solid-state semiconductor device with four layers of alternating P- and N-type materials used for high-power applications. It acts exclusively as a bistable switch (or a latch), conducting when the gate … Se mer The silicon controlled rectifier (SCR) or thyristor proposed by William Shockley in 1950 and championed by Moll and others at Bell Labs was developed in 1956 by power engineers at General Electric (G.E.), led by Gordon Hall and commercialized by G.E.'s Frank W. "Bill" … Se mer TRIAC The functional drawback of a thyristor is that, like a diode, it only conducts in one direction so it can't be safely used with AC current. A similar self-latching 5-layer device, called a TRIAC, is able to work in both directions. This … Se mer The thyristor is a four-layered, three-terminal semiconductor device, with each layer consisting of alternating N-type or P-type material, … Se mer 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 … Se mer Thyristor manufacturers generally specify a region of safe firing defining acceptable levels of voltage and current for a given operating temperature. … Se mer In recent years, some manufacturers have developed thyristors using silicon carbide (SiC) as the semiconductor material.
