thyristor (plural thyristors)
(electronics) A semiconductor diode having an extra "gate" terminal to switch it on.
Additional passive components such as grading capacitors and resistors need to be connected in parallel with each thyristor in order to ensure that the voltage across the valve is evenly shared between the thyristors. Source: Internet
In the indirect optical triggering method, low-voltage control electronics send light pulses along optical fibres to the high-side control electronics, which derives its power from the voltage across each thyristor. Source: Internet
This results from requiring the AC circuit to turn off the thyristor current and the need for a short period of 'reverse' voltage to effect the turn-off (turn-off time). Source: Internet
The 85 existing 1992-stock trains are the most unreliable on the London Underground as they are equipped with the first generation of solid state direct current thyristor control traction equipment. Source: Internet
The first complete HVDC scheme based on thyristor valves was the Eel River scheme in Canada, which was built by General Electric and went into service in 1972. Source: Internet
The thyristor plus its grading circuits and other auxiliary equipment is known as a thyristor level. Source: Internet
