INTRODUCTION

ACTIVE HARMONIC FILTER

iKonMac Active Harmonic Filter is an advanced power electronics device designed to dynamically monitor and compensate harmonic distortion. Harmonics are commonly caused by non-linear loads such as variable frequency drives, UPS systems and industrial automation equipment.

By injecting counteracting currents in real time, AHF eliminates harmonics, improves power factor and corrects load imbalances. Unlike passive filters, it is programmable, fast-responding and adaptable to changing load conditions.

As a leading Active Harmonic Filter manufacturer in China, iKonMac helps industrial users enhance stability, efficiency and equipment lifespan while supporting compliance with strict power quality requirements.

FEATURES

Compensate 2-50th Harmonics.

Prevent Malfunctions & Measurement Errors

Minimize Resonance & Fault Risk

Extend Cable Lifespan THDi < 5%

Eliminate Electromagnetic Interference

Ensure Compliance & Avoid Shutdowns

CORE ADVANTAGES

Extremely High Protection Ability

The design features a layered structure, separating the electronic and power components. The electronic layer ensures insulation, moisture and dust protection, while the power layer is fan-cooled for harsh industrial environments.

7th Generation Infineon IGBT

Seventh generation Infineon IGBT technology reduces switching loss and supports high switching frequency with fast PWM calculation.

Full FPGA Control Chip

The control system uses FPGA architecture with parallel-running hardware CPU units, improving dynamic compensation calculation.

Low Noise 60dB

Optimized reactor design and high switching frequency reduce fan and switching noise for stable industrial operation.

Low Power Consumption <2.5%

Lower switching loss and compact inductance size help the cabinet maintain efficient continuous operation.

Full Load Ambient 55C

Layered heat dissipation and high temperature resistant components support operation in demanding industrial sites.

Intelligent Prevention of Resonance

Intelligent startup and protection logic reduce resonance risk when working with complex loads and existing capacitor equipment.

High Power Density 800A/675kVar

Standard modular design supports compact cabinet integration for high-density AHF or SVG capacity in large industrial projects.
