The thyristor is a solid-state semiconductor device similar to the diode, but with an extra control terminal that is used to switch the device on at a defined instant. Because thyristors have breakdown voltages of only a few kilovolts each, HVDC thyristor valves are built using large numbers of thyristors connected in series.
The state's grid operator, the Electric Reliability Council of Texas (ERCOT), predicted demand would jump from 57,486 megawatts on Friday to 71,893 MW on Monday, 72,725 MW on Tuesday, and 74,346 ...
