Abstract
A thyristor-controlled capacitor bank includes a thyristor switch and a capacitor bank. The capacitor bank is split into at least two series-connected capacitor groups. A series circuit including a thyristor switch and an inductor coil is connected in parallel with the capacitor group which is remote from a capacitor group at a mains power supply connection. A thyristor-switched capacitor bank is thus obtained which has a thyristor switch that therefore only needs to be constructed for a fraction of the mains power supply voltage itself, which is a major advantage for economic reasons.
