APFC, SVG and Hybrid SVG address reactive power compensation in different ways. Learn how to review load variation, power factor, harmonics, system wiring and site data before selecting a solution.

Choosing an active harmonic filter requires more than matching a current rating. This guide explains the site data, system configuration, installation format, and product features engineers should review before selecting an AHF for industrial power systems.

BANGKOK, THAILAND — To ensure the smooth operation of customer power systems and optimize grid performance, a senior engineering team from Shanghai Intone Power Co., Ltd. (Intone Power) recently traveled to Thailand to perform comprehensive on-site debugging, testing, and technical training.

Variable Frequency Drives (VFDs) have revolutionized industrial automation. By regulating motor speed and torque to match real-time demand, VFDs significantly reduce energy consumption, enhance process control, and extend machinery lifespan across pumps, fans, compressors, and conveyers.

As electric vehicles (EVs) become more common worldwide, the demand for reliable and efficient charging infrastructure continues to grow. While EV charging stations offer significant environmental and economic benefits, they also introduce new challenges to electrical power systems. One of the most critical issues is harmonic distortion. If left unmanaged, harmonics can reduce power quality, increase equipment losses, and shorten the lifespan of electrical components.

1. Power Quality Issues in Modern Power Systems

Modern industrial power systems commonly use nonlinear loads.

Typical devices include VFDs, UPS units and LED lighting systems.

These devices improve production efficiency. However, they hurt overall power quality.

Nonlinear loads produce various order harmonic currents.

These harmonics accumulate in thepower system. They distort electrical waveforms and pollute the grid.

This problem also lowers the system’s overall power factor.

Traditional power correction tools cannot solve harmonic issues well.

The Active Power Filter (APF) can fully eliminate harmonic interference. It can also mitigate harmonic distortion in industrial environments.

SVG for commercial buildings is used to improve power factor correction, reduce reactive power, and support voltage stability. Modern commercial buildings use HVAC systems, elevators, pumps, lighting, UPS systems, and office equipment. These loads change throughout the day.

SHANGHAI, China – May 28, 2026 – Intone Power, a premier innovator in industrial power electronics and grid stabilization solutions, today announced the successful energization of its state-of-the-art power quality correction systems at a massive municipal water reclamation facility in East China. The deployment of Intone Power's advanced Active Power Filters (APF/AHF) and Static Var Generators (SVG) marks a critical development in China’s ongoing drive to integrate high-efficiency automation into its public utility sectors.
