In the capacitive modulation mode, shown in Fig. 5, the thyristor valve is turned on for a short period of time just prior to the voltage zero crossing at the 180 electrical degree point of the capacitor voltage (shortly before the maximum current through the capacitor). The capacitor will then discharge through the thyristors and the reactor.
