Product Details
1.Product Description
SVG Static Var Generator PFC series is a product aimed for Power Factor Correction, Harmonic Filtering along with Three-phase Balancing Function. CoEpower SVG can do bi-directional power factor correction, PF from 1.0 inductive to 1.0 capacitive. Benefiting from inverter technology, SVG Static Var Generator PFC series’ compensation is stepless, which means SVG output shall match the system reactive power, no over-compensation or under compensation. For single module, SVG capacity ranges from 30kvar to 100kvar. For cabinet system, it's unlimited parallel design.

4.How CoEpower Active Harmonic Filter works
External CT detects the load current, DSP tracks instruction current and calculates the reactive power change rate through the Instantaneous Reactive Power Algorithm. Then DSP sends PWM signal to IGBT driving board which can control IGBT on and off to generate inductive or capacitive compensation current. At the same time CT detects the output current and compensation result is fed back to DSP, then the next round of logic control is carried out to realize stable power grid.
5.Compensation effect
IGBT DSP control system make the reactive power compenastion from mechanical compensation evolve to intelligent power electronic stability compensation.Whatever the load current changes, SVG can always output corresponding compensation current to realize the perfect compenstion.Always keeps the power factor as 0.99.Running well in severe environment like high THDU/high ambient tempertaure/high amplitude.
