Operating Principle of the SVG

The Sinopak SVG represents the latest generation technology in the power factor correction field. It operates by detecting the load current on a real-time basis through an external CT’s and determining the reactive content of the load current. The data is analysed and the SVG’s controller drives the internal IGBT’s by using pulse width modulation signals to make the inverter produce the exact reverse reactive current of the corresponding load reactive content. This is injected to the grid to compensate the reactive content of the load current. By adjusting the output voltage amplitude and phase angle or by directly controlling the AC side current, the SVG can absorb or generate var according to the load reactive power or the grid voltage level.
