Thyristor Controlled Series Capacitor (TCSC)
The capacitor is getting charged/discharged (depending on the switching instant) by the line current which will act as a constant current source. The charging of the capacitor is reversed during the resonant half-cycle of the LC circuit. Therefore, the resonant charge reversal produces the DC offset in capacitor voltage.
