On 2 June 2026, Hengfu Power officially received a utility model patent certificate issued by the National Intellectual Property Administration for its independently researched, developed and designed ‘Integrated Switching Power Supply with Hybrid Frequency and Pulse Width Modulation’. The patent application for this technology was filed on 30 April 2025. Following examination by the National Intellectual Property Administration and the publication of the grant notice, the patent certificate was issued. This represents a major new achievement for Hengfu, resulting from its deep commitment to core switch-mode power supply technologies and its dedication to independent research, development and innovation.

The utility model patent certificate is an authoritative document recognised by the state as proof of innovation in product structure and circuit design, focusing on three core areas: optimisation of practical performance, enhancement of structural reliability, and breakthroughs in differentiated circuit design. With over thirty years’ deep expertise in the switching power supply industry, Hengfu has consistently prioritised R&D-driven development, systematically establishing proprietary patent technologies and implementing them across its full range of power supply product designs: from optimising wide-temperature circuit architectures and refining high- and low-voltage isolation structures, to reducing noise in high-frequency integrated power supplies and enhancing energy efficiency. The company continues to build core technical barriers for switching power supplies that combine stability, compatibility and high adaptability, forming a comprehensive technology commercialisation system encompassing “R&D project initiation – patent portfolio development – Product Implementation’ complete technology conversion system.

From adopting industry-standard solutions to holding proprietary core circuit patents, this persistent commitment to technological excellence is not only Hengfu’s core competitive advantage in expanding the industrial power supply market, but also a true reflection of domestic power supply manufacturers’ dedication to independent innovation and their efforts to break free from reliance on externally sourced solutions. Amid the wave of development towards high-end manufacturing and localisation, only by maintaining long-term investment in technology and continuously accumulating original patent achievements can companies continually refine high-performance power supply products and consolidate their leading position in the industry amidst fierce market competition.
