WebConventional series-connected High Voltage Direct Current (HVDC) thyristors are triggered electrically (referred to as ETTs). Using Light-Triggered Thyristors (LTTs) instead, valve electronics can be considerably simplified. WebApr 9, 2024 · A thyristor is a four-layer solid-state semiconductor device having alternating P- and N-type materials. It only functions as a bistable switch, conducting when the Gate gets a current trigger and continuing to conduct until the voltage across the device is reversed biased or removed (by some other means). There are two designs, which differ …
