SVG adopts a cascaded multi-level H-bridge power unit configuration, utilizing turn-off capable high-power power electronic devices (such as IGBTs) to form a self-commutated bridge circuit. It is connected in parallel to the power grid through a reactor (or step-up transformer). By appropriately adjusting the amplitude and phase of the AC-side output voltage of the bridge circuit or directly controlling the AC-side current, the system can absorb or generate reactive current that meets grid requirements, achieving dynamic reactive power compensation.

Explanation
No Load Operation Mode
When Ui = Us, SVG does not provide compensation
Inductive Operation Mode
When Ui < Us, SVG is equivalent to a continuously adjustable inductance
Capacitive Operation Mode
When Ui > Us, SVG is equivalent to a continuously adjustable capacitor
