Active filter APF electrical cabinet power solution

Basic Introduction

In this project, to solve this problem, we launched an electrical cabinet with integrated active filter.

This Product combines advanced power electronics technology and intelligent control system,

which can effectively filter harmonics, compensate reactive power, and improve three-phase imbalance,

ensuring the stability and reliability of the power distribution system.

Working Principle

The active filter cabinet is based on active power filter (APF) technology.

By real-time detection of harmonic components in load current,

it dynamically injects reverse compensation current to achieve harmonic suppression,

reactive power compensation and three-phase imbalance control.

Compared with traditional passive filters.

Product Features

High-efficiency filtering: It can dynamically filter 2~50 harmonics, and the filtering accuracy is as high as 97% or more.

Fast response: The response time to load fluctuations is less than 1ms, and it can quickly adapt to system changes.

Intelligent control: It adopts DSP full digital control, with functions such as automatic detection, reactive power compensation, and resonance suppression.

Modular design: It supports multiple units in parallel operation and can flexibly expand capacity according to demand.

Energy saving and protection: improve system power factor, reduce line loss, and have multiple protection functions such as overcurrent and overvoltage.
