SVG vs APF: What is the Difference Between Static Var Generator and Active Power Filter?

Many customers are confused about SVG and APF. Although both belong to power quality equipment, their functions are different.

 Static Var Generator (SVG)
Main function: Dynamic reactive power compensation, stabilize voltage, solve power factor problems.
Suitable for: Wind farms, photovoltaic power stations, loads with large voltage fluctuation.

 Active Power Filter (APF)
Main function: Detect and filter out grid harmonics in real time.
Suitable for: Industrial factory, data center, equipment that produces lots of harmonic current.

Suggestion: Many new energy projects use SVG + APF together to solve both reactive power and harmonic issues at the same time.

Shanghai Nengdu New Energy manufactures both SVG and APF. We can recommend suitable products according to your actual grid conditions. Feel free to send your power parameters for our technical evaluation.
