Hybrid APFC Systems

Smart Hybrid APFC System

PQI’s Smart Hybrid APFC System is a next-generation power factor correction solution that intelligently combines conventional APFC (capacitor banks) with advanced Static VAR Generator (SVG) technology. This hybrid approach delivers precise, real-time reactive power compensation, ensuring near-unity power factor even under rapidly fluctuating and non-linear load conditions.

Designed for modern Indian industries, Hybrid APFC Systems not only reduce reactive power penalties but also improve waveform quality, minimize harmonics, and enhance overall energy efficiency. The result is stable power quality, lower losses, and extended life of electrical equipment.

What is a Hybrid APFC System?

A Hybrid APFC System is an intelligent reactive power compensation solution that integrates passive correction (APFC capacitor banks) with active compensation (SVG). While capacitor banks handle steady-state reactive power, the SVG responds instantly to dynamic load variations, delivering fast and accurate correction.

This active + passive combination ensures superior power factor correction, harmonic mitigation, and stable voltage profiles—making Hybrid RTPFC Panels ideal for industries with rapidly changing loads, VFDs, UPS systems, welding machines, and other non-linear equipment.
