LV Static Var Generator (SVG)

General electric energy quality control equipment

The low-voltage SVG is a modular product designed by ACTIONPOWER for traditional commercial and industrial customers. It refers to the method of connecting a self-commutated bridge circuit directly in parallel with the electric grid through a reactor. By adjusting the phase and magnitude of the output voltage on the AC side of the bridge circuit, or by directly controlling its AC side current, the circuit actively generates the required reactive current, achieving the purpose of dynamic reactive power compensation.
