METHOD OF DISCONNECTING A THYRISTOR-SWITCHED CAPACITOR BATTERY, AND A THYRISTOR-SWITCHED CAPACITOR BATTERY

摘要

A thyristor-switched capacitor battery comprising a thyristor switch comprising at least one thyristor, and a capacitor, cascaded with each other; and a coil cascaded with the thyristor switch and the capacitor; and an auxiliary energy source, preferably an auxiliary capacitor, connected in parallel with the coil. The auxiliary capacitor is charged until the amount of energy in it corresponds to the amount of energy accumulated in the coil, and the thyristor switch is turned off at a predetermined moment by controlling the thyristor switch voltage to be negative for a predetermined safety period by discharging the voltage charged in the auxiliary capacitor to the coil.
