Core R & D Concept
We focus on real industrial working conditions and take actual on-site problems as the starting point for technical research and development.
Technology-driven, Application-oriented
Different from general product upgrading, our R & D focuses on harsh industrial scenarios including mining, marine, power and petrochemical industries. Every technical optimization is based on actual site pain points, ensuring higher stability, stronger overload resistance and lower failure rate for industrial MV/HV VFDs.
Four Major R & D Processes
We implement a complete closed-loop R & D system from theoretical simulation to product iteration to guarantee industrial-grade reliability.
Technical Research & Simulation
Carry out topology optimization, algorithm simulation and industrial scenario modeling. Complete theoretical verification of three-level inverter structure, harmonic suppression and load adaptive control.
Prototype Development & Design
Complete independent hardware design, software programming and structural optimization. Customize industrial-grade circuit structure and strong anti-interference control logic for heavy-duty working conditions.
Full Performance Testing
All prototypes pass full-load aging test, high & low temperature test, vibration test and harmonic detection. Strictly verify stability, energy efficiency and reliability before mass production.
Product Iteration & Upgrade
Collect global project operation data, continuously optimize control algorithms and product details, and launch upgraded versions to adapt to increasingly complex industrial working conditions.
R & D Strength Data
We rely on independent intellectual property rights, professional teams and complete laboratories to support customized R & D.
