Recently, INVT achieved a major technological breakthrough with the successful launch of its independently developed 30MVA medium-voltage water-cooled variable frequency drive (VFD) system.

This milestone not only fills an industry gap but also provides new opportunities for industrial drives with its advantages of high reliability, long service life, and energy efficiency.

Independent Innovation Filling Market Gaps

From blueprints to final delivery, INVT’s R&D team overcame multiple technical challenges to release the industry’s first 30MVA medium-voltage water-cooled VFD.

From algorithm breakthroughs to prototype iterations, from late-night lab experiments to the sweat of production lines, every step embodied technical dedication and persistence. The production team maintained “millimeter-level precision” to ensure optimal delivery, injecting new momentum into industrial drives and advancing the industry forward.

Four Core Advantages Redefining Industry Benchmarks

As a key national technology, the 30MVA medium-voltage water-cooled VFD system can be widely applied in metallurgy, mining, oil, chemical, new energy, power, and water conservancy. Its innovations shine in four main areas:

1. Solid Foundation through Rigorous Selection
Critical components were carefully chosen from leading global brands. High-quality, long-life film capacitors significantly reduce failure rates, cut maintenance costs, and extend equipment lifespan.
The unique water-cooling design greatly reduces heat on radiators and power units, dramatically extending overall service life.

2. Stable and Precise Operation
Using a cascaded unit design, the rectifier achieves 48-pulse rectification with 37-level line voltage output, ensuring lower harmonics without additional filters.

Proprietary motor control algorithms enable independent control of excitation and torque currents, ensuring stable motor operation.
Strong overload capacity allows the system to handle transient load impacts with ease, improving production continuity. Robust EMC design keeps the system interference-free and maintains stability.

3. Comprehensive Safety Protection
With unit redundancy, the system can bypass faulty modules and continue operating under derated conditions.

Ride-through capability ensures stability during grid fluctuations.
Dual redundant control power supplies guarantee uninterrupted operation.
IoT monitoring allows real-time status checks and sends instant alerts, shifting from passive inspection to proactive protection.

4. Green and Sustainable Operation
Optimized transformer magnetic circuits and efficient water cooling ensure high-efficiency operation, reducing long-term operating costs and enabling sustainable growth for energy-intensive industries.

Forging Ahead with Innovation

INVT continues to see innovation as the sail that drives progress and quality as the helm guiding direction. Looking forward, INVT will keep advancing technological breakthroughs and product upgrades, enhancing competitiveness, and contributing to global industrial sustainability.
