10~100kVAr SVG Advanced Static Var Generator

How SVG Works?

The Static Var Generator (SVG) is a power electronics-based device connected in parallel with loads requiring harmonic mitigation. Operating as a controlled current source, the SVG dynamically adjusts to any current waveform in real-time.

When loads generate inductive or capacitive currents, they cause the load current to lag or lead the voltage. Detecting the phase angle difference, the SVG promptly injects leading or lagging currents into the electric power system. This aligns the current's phase angle closely with that of the voltage, bringing the fundamental power factor close to unity.
