It consists of a power capacitor connected in series with a bidirectional thyristor valve and, usually, a current limiting reactor (inductor). The thyristor switched capacitor is an important component of a Static VAR Compensator (SVC), where it is often used in conjunction with a thyristor controlled reactor (TCR).

Why does a thyristor valve have a lower impedance than a capacitor?

The controlled reactor has a significantly lower impedance than the capacitor so that when the thyristor valve is fully conducting, the overall impedance of the capacitor section becomes inductive; the current through the reactor is greater than the line current and the capacitor current is smaller.
