            UNT-SVG low voltage static reactive generator


            Low-voltage static reactive power generator (SVG: Active Power Filter) is aimed at reactive power compensation of 400V standard power grid in China. Our company has launched independent intellectual property rights and innovative SVG power electronic device system. The system uses international advanced three-level technology to enable dynamic reactive power compensation and improve grid power factor.

            SVG is connected to the grid in parallel. By detecting the harmonic components of the load in real time, the PWM transform technology is used to inject the current with the same harmonic and component magnitude and opposite direction into the power supply and distribution system. The device that implements the harmonic suppression function enables the power supply system to meet the requirements of GB/T 14549-93 Power Quality Shared Grid Harmonics.
