A thyristor controlled reactor is usually a three-phase assembly, normally connected in a delta arrangement to provide partial cancellation of harmonics.Often the main TCR reactor is split into two halves, with the thyristor valve connected between the two halves.
Thyristor-controlled reactor (TCR), shown with delta connection Thyristor-switched capacitor (TSC), shown with delta connection The thyristors are electronically controlled. Thyristors, like all semiconductors, generate heat and deionized water is commonly used to cool them. [ 5 ]
The thyristor switched capacitor is an important component of a Static VAR Compensator (SVC), [1] [2] where it is often used in conjunction with a thyristor controlled reactor (TCR). Static VAR compensators are a member of the Flexible AC transmission system (FACTS) family.
When arranged to do this, the TSR is referred to as a Thyristor Controlled Reactor (TCR). TCRs produce large amounts of harmonics and require Filter Banks to prevent adverse effects to the system. Another type of shunt compensation is the Static Synchronous Compensator or STATCOM. Power electronics are combined in series with a reactor to form ...
A thyristor (/ θ aɪ ˈ r ɪ s t ər /, from a combination of Greek language θύρα, meaning "door" or "valve", and transistor [1]) is a solid-state semiconductor device which can be thought of as being a highly robust and switchable diode, allowing the passage of current in one direction but not the other, often under control of a gate electrode, that is used in high power applications ...
Connected to a reactor and switched sub-cycle allowed the effective inductance to be varied. The thyristor also greatly improved the control system, allowing an SVC to detect and react to faults to better support the system. [8]

The miniature RK61/2 thyratron marketed in 1938 was designed specifically to operate like a vacuum triode below its ignition voltage, allowing it to amplify analog signals as a self-quenching superregenerative detector in radio control receivers, [6] and was the major technical development which led to the wartime development of radio ...
