Shanghai, January 9, 2026 — As industrial facilities and data centers worldwide grapple with escalating harmonic distortion from modern power electronics, Shanghai Yingtong Electric Co., Ltd. (YT ELECTRIC) today announced the enhanced rollout of its high-performance Active Harmonic Filter (AHF) solutions—designed to deliver real-time harmonic mitigation, improve energy efficiency, and prevent costly equipment failures.

With non-linear loads such as variable frequency drives (VFDs), uninterruptible power supplies (UPS), and EV chargers now ubiquitous across manufacturing, ports, and renewable energy sites, total harmonic distortion (THD) has become a silent threat to power reliability. Left unaddressed, harmonics can cause transformer overheating, circuit breaker trips, and premature failure of sensitive electronics.
“Harmonics are no longer a niche issue—they’re a daily operational risk,” said Li Wei, Chief Technology Officer at YT Electric. “Our latest AHF systems respond in under 100 microseconds to neutralize harmonics from the 2nd to the 50th order, ensuring THD stays below 5% and compliance with IEEE 519 standards. This isn’t just about power quality—it’s about business continuity.”
Proven Performance Across Critical Sectors
Recent deployments highlight the impact of YT Electric‘s AHF technology:
In a Tier-III data center in Germany, AHF installation reduced voltage THD from 18% to 3.2%, eliminating unexpected server reboots.
At an automotive plant in Mexico, AHF integration cut motor maintenance costs by over 30% within six months.
A solar-plus-storage project in Australia used Yingtong AHF to meet strict grid code requirements and avoid curtailment penalties.
Unlike traditional passive filters—which are fixed, narrowband, and prone to resonance—Yingtong’s AHF uses advanced DSP control and IGBT-based inversion to dynamically adapt to changing load conditions. The system supports modular expansion, cloud-based remote monitoring, and seamless coordination with SVG and capacitor banks for comprehensive power quality management.
Built for Global Scalability and Service
All YT Electric AHF units are CE, TÜV, and ISO certified, with designs validated in over 30 countries. The company offers end-to-end support—from harmonic audits and simulation modeling to on-site commissioning and 24/7 technical assistance.
“Our clients don’t just buy a device—they gain a power quality partner,” added Li. “Whether you’re upgrading an aging facility or building a new microgrid, our team ensures your AHF solution is precisely tailored to your electrical profile.”
Free Harmonic Assessment Now Available
To help facilities identify hidden risks, YT Electric is offering a complimentary harmonic audit to qualified industrial and commercial clients through Q2 2026. The service includes load analysis, THD simulation, and a customized AHF recommendation—no obligation.
