CoEpower special design SVG offers a Target PF working mode, it regulates the PF power factor to the setting value in the HMI in real-time subject to users’ settings, It detects the load current through an external current transformer CT, and then it analyzes the load required reactive power current value by DSP control program in real-time, then generates PWM signal to IGBT inverter to output an opposite direction but same value current to offset the reactive current to meet the target power factor.

● The component concept designs SVG and can make compensation for both capacitive and inductive loads, thus obtaining a compensation effect with the level of PF 0.99 and avoiding over-compensation and under-compensation
● The complete response time of SVG is less than 10 Ms, and the dynamic response time is less than 50 μs, making SVG a top pick for a fast-changing environment.
● The capacitor that comes with the SVG does not require the installation of a filter bank; therefore, resonant amplification will not happen. In addition, as an active compensation device and a current source device adopting such cut-off components as IGBT, SVG wards off resistance from the perspective of the mechanism, significantly improving completeness.
● SVG can continuously adjust reactive power dynamically and bi-directionally (-1 to +1); that is to say, SVG can output reactive power constantly in both rated capacitive and rated inductive working conditions, and it can make constant compensation in a wide range if combined with a fixed capacitor.
● SVG does not need a large-capacity capacitor or reactor to serve as energy storage elements, and the area it occupies is just half of that occupied by other types of dynamic compensation assemblies with the same capacity, or even a smaller area. Moreover, SVG adopts modular design and cabinet-type installation, which demands only a few efforts in engineering design and installation.
● SVG is designed with an active compensation circuit; therefore, the voltage of the grid has little influence on the compensation capacity. The output of reactive current matches the working condition even when the voltage of the power grid is low.
● SVG has low power loss and needs little maintenance, so the chances of resonance overvoltage are pretty low. The service life lasts for over ten years (with an MTBF longer than 100,000 hours).
● High efficiency >97%

Um gerador de var estático, also known as a Static Var Compensator (SVC) or Active Power Factor Correction device, is an advanced electrical device used to improve power quality in electrical systems. It helps correct power factor, reduce reactive power, and balance voltage.
How Does It Work?
When electrical equipment like motors, compressors, or welding machines run, they often draw reactive power (non-usable power). This causes a low power factor, which leads to:
-Wasted energy
-Higher electricity bills
-Overloaded cables and transformers
The Static Var Generator continuously monitors your power system in real time. It then injects or absorbs reactive power instantly, like a shock absorber for your electricity, to keep the power factor close to 1.0 (ideal).
What Happens Step-by-Step?
Measurement: The SVG measures voltage, current, and power factor many times per second.
Calculation: It calculates how much reactive power is needed (positive or negative).
Injection: Using power electronics (like IGBTs), it injects or absorbs that exact amount of reactive power.
Correction: This keeps your power factor stable and your system efficient, automatically and in real time.
Benefits for You
Lower electricity bills (by avoiding penalties)
Better equipment life (due to stable voltage)
Reduced heat and losses in cables
Compliance with utility power factor requirements
In Summary, think of a Static Var Generator as a smart helper in your power system. It keeps your electricity “clean” and efficient by correcting imbalances, so you save money and protect your equipment.
(1) Improved Power Factor
Maintains power factor close to 1.0, automatically.
Avoids penalties from utility companies for low power factor.
Ensures efficient use of electrical energy.
(2) Reduced Reactive Power Flow
Eliminates or greatly reduces the amount of reactive power in the system.
Frees up capacity in transformers and cables for real (active) power.
Less heat generation and energy loss in the system.
(3) Enhanced Equipment Performance
Stabilizes voltage, reducing stress on motors, drives, and sensitive equipment.
Increases the lifespan of electrical components by reducing wear and tear.
Minimizes nuisance tripping of breakers and protective devices.
(4) Real-Time, Dynamic Compensation
Responds in milliseconds, much faster than traditional capacitor banks or reactors.
Adapts instantly to changing loads—ideal for variable or heavy industrial equipment (e.g., welders, cranes, elevators).
(5) Cost Savings
Lower electricity bills by improving power factor and reducing energy losses.
Delays or avoids the need for upgrading transformers or cables.
Helps in achieving compliance with grid codes and utility standards.
(6) Energy Efficiency & Sustainability
Helps reduce the overall carbon footprint by reducing wasted energy.
Supports green building and energy efficiency certifications (e.g., LEED).
(7) Easy Integration
Compatible with low-voltage and medium-voltage systems.
Can be installed in parallel, without modifying existing equipment.
In Summary, using a Static Var Generator offers a smart, fast, and energy-efficient way to manage reactive power, stabilize your electrical system, and save costs—all while improving reliability and sustainability.
