Hybrid Solution with Stepless Reactive Power Compensation (APFC+SVG)

With the invention of switching logic, it is possible to achieve automatic control of reactive power compensation. Despite the means are available for achieving dynamic reactive power compensation, there is a limit to have fine control due to fixed-step rating in APFC panel. The need for intermediate fine control of reactive power including real-time can be catered through stepless switching technology called SVG or static – VAR – Generator.
The advanced stepless technology consists of active device IGBT, the product can be effectively applied when combined with a normal APFC system. This combined hybrid solution of (Stepless + Step) switching forms the LV SVGC system.

The product consists of SVG modules and LC (reactor – capacitor) steps, which are monitored by controlled by Advanced multi-level controller. The controller effectively utilizes the combination to cater and fine-tune the need for reactive power compensation at all the times.
