Static Var Generator (SVG) & Advanced Static Var Generator (ASVG)
Our static reactive power compensators (SVG) provide an optimal solution for issues related to network stability, power factor, and reactive power demand in various industrial applications. The devices feature extremely fast operation, compact design, and exceptional cost efficiency, ensuring immediate response to disturbances in medium- and low-voltage power systems. By compensating reactive power, they significantly increase the lifespan of installations, enhance the reliability of production processes, improve system performance, and reduce transmission losses, all while meeting the most stringent energy quality standards.

Product Description
The consumption of reactive power involves additional charges levied by operators, which is why the use of an SVG compensator effectively reduces electricity bills, completely eliminating the costs associated with reactive power consumption.
- Immediate and precise reactive power compensation
- Active harmonic suppression
- Dynamic adaptation to changing operating conditions
SVG principle of operation
The operating principle of the SVG compensator is based on continuously monitoring the current and voltage waveforms in the network.
When the system detects phase deviations caused by the nature of the load, it immediately generates a compensating current with the opposite characteristics. Thanks to the use of German IGBT modules from Infineon and precise PWM control, the device corrects the power factor in real time, compensating both inductive and capacitive reactive power. This active mode of operation ensures the maintenance of ideal power supply parameters regardless of load fluctuations, guaranteeing exceptional reliability and the highest precision of compensation.

SVG / ASVG product-resource hub
Static Var Generator (SVG) and Advanced Static Var Generator (ASVG) are product-line terms for dynamic reactive-power compensation projects. CNBYG evaluates the required response, reactive-power range, connection conditions, load variation, existing equipment, and installation constraints with the project data. A product page is not a guarantee of power-factor, voltage, or compliance performance.
Application entry points
EV charging and voltage fluctuation
Charging profiles and upstream conditions should be reviewed at the project connection point.
Photovoltaic inverter applications
Separate reactive-power and harmonic objectives before specifying equipment.
Marine and shipbuilding
Review shore-power, welding, and installation constraints for the relevant vessel or yard project.
SVG / ASVG selection inputs
- Single-line diagram, nominal voltage, frequency, transformer capacity, and installation location
- Reactive-power profile, power-factor objective, load variation, and relevant voltage data
- Existing capacitor banks, reactors, filtering equipment, protection, and control interfaces
- Environmental, enclosure, thermal, cable, and commissioning constraints
For systems with a separate harmonic-current issue, review the AHF/APF product hub and determine whether the objectives require coordinated equipment.
