SiC-powered harmonic filtering
for heavy industry

GRIDSINE-X is the dedicated active harmonic filter variant of the Premium SiC Series — built on Silicon Carbide switching technology with specialized AHF firmware for ultra-fast harmonic elimination across 220V to 380V heavy industrial systems.

With module capacities from 20A to 200A and filtering effectiveness of up to 98%, GRIDSINE-X reduces THDi to below 5% at the point of common coupling — with a 4 µs instantaneous response time that eradicates transient harmonics before they propagate.

Covering the 2nd through 51st harmonic orders with independent per-order selection, GRIDSINE-X targets the specific harmonic signatures produced by arc furnaces, large presses, crane drives and other severe non-linear loads.

Why SiC Changes Everything

Six Reasons GRIDSINE-X Outperforms IGBT

Silicon Carbide delivers harmonic filtering performance that IGBT-based systems cannot match — especially in heavy industrial environments.

4 µs Instantaneous Response

SiC reacts to arc furnace transients, crane impacts and large press cycles in just 4 microseconds — cancelling harmonic disturbances before they propagate into the grid.

> 100 kHz Switching Frequency

SiC switches at > 100 kHz — producing compensation current far closer to a perfect sine wave. Higher switching frequency means more precise harmonic cancellation at every order.

2nd–51st Harmonic — Independent Selection

Filters the complete harmonic spectrum from the 2nd to the 51st order. Each order can be individually enabled or disabled — allowing exact tuning to your load profile.

up to 98% Filtering Effectiveness

Near-complete harmonic elimination at rated capacity. Reduces THDi to below 5% at PCC even in the most demanding arc furnace and rolling mill environments.

Smart Rotation Redundancy

Up to 10 modules with smart rotation distribute operating hours equally. Faulty modules auto-isolate while remaining modules increase output — zero downtime.

Bluetooth + Mobile APP Control

All operating parameters — harmonic priorities, filtering targets, load sharing ratios — can be configured and monitored via the GRIDSINE-X mobile application on any smartphone.

Applications

Where GRIDSINE-X Is Specified

When standard IGBT-based AHF systems reach their limits — GRIDSINE-X delivers SiC-speed harmonic elimination.

AF

Steel & Arc Furnaces

The most demanding harmonic environment. 4 µs SiC response eradicates arc furnace harmonics before they affect neighbouring equipment or cause voltage distortion.

RM

Rolling Mills

Combination of large motor drives, crane systems and high harmonic generation. Independent per-order selection targets the exact harmonic spectrum of each load.

DC

Data Centers

Large UPS input stages with severe harmonic injection. Independent per-order harmonic control meets the strictest utility grid code requirements.

H

Hospitals

Medical imaging suites and critical power systems where harmonic distortion can cause equipment malfunction and measurement errors.

A

Automotive

Welding lines, paint line rectifiers and large press drives produce severe transient harmonics that only SiC response speed can effectively cancel.

SC

Semiconductor

Clean room process equipment demands ultra-clean power. up to 98% filtering effectiveness with SiC precision ensures supply quality for sensitive processes.

CB

Commercial Buildings

Large commercial complexes with concentrated non-linear loads — LED lighting, IT infrastructure and HVAC drives generating cumulative harmonics.

RE

Renewables

Grid-connected solar and wind farms at the point of common coupling. Harmonic compliance and reactive support in a single SiC-powered active module.
