Dr. William: A Technology Pioneer Powering the Evolution of China’s Power Semiconductor Industry
The rapid growth of electric vehicles, industrial automation, renewable energy, and high-efficiency power electronics has placed unprecedented demands on power semiconductors. Behind China’s transition from technology follower to global contender in this field stands a group of pioneering engineers—among them, Dr. William, a leading force in power module innovation and semiconductor industrialization.
From Academic Excellence to Global Power Semiconductor R&D
Dr. William graduated from Tsinghua University, where he developed a strong foundation in electronic engineering and semiconductor theory. His professional journey began at Mitsubishi Electric’s global power semiconductor design center in Fukuoka, Japan, a world-class hub for IGBT modules, power MOSFETs, and advanced power module packaging.
At Mitsubishi Electric, he worked directly on cutting-edge power semiconductor R&D, contributing as a core inventor of power module technologies. This experience provided him with deep insight into device integration, thermal management, and long-term reliability—skills essential for large-scale power semiconductor manufacturing. He became one of the earliest Chinese experts to fully master the industrialization of power semiconductors at a global standard.
Breaking New Ground: HVIC and Intelligent Power Modules (IPM)
After returning to China, Dr. William joined Silan Microelectronics and took on a key role in China’s national “02 Special Project” for integrated circuits. Under his technical leadership, the team successfully developed China’s first High-Voltage Integrated Circuit (HVIC) and Intelligent Power Module (IPM).
These innovations marked a turning point for China’s high-end power semiconductor chips, enabling domestic solutions for industrial inverters, motor drives, HVAC systems, and automotive power electronics. The achievement represented a critical shift—from dependence on imported technology to independent innovation.
Scaling Innovation: Power Semiconductor Manufacturing and Standards
In 2011, Dr. William joined Midea Group, a Fortune Global 500 company, serving as Director of Semiconductor Technology and Head of the Semiconductor Research Institute at Midea’s Central Research Institute. His focus extended beyond R&D to the full value chain of power semiconductor module manufacturing.
Key contributions include:
- Establishing China’s first fully self-developed power semiconductor module mass-production line, covering design, packaging, testing, and high-volume manufacturing
- Leading the drafting of China’s first national standard for power semiconductor modules, setting benchmarks for performance, safety, and reliability
- Authoring over 800 patents related to power semiconductor integration, earning the China Patent Award for four consecutive years and recognition as a “Guangdong Inventor”
These milestones laid the foundation for scalable, reliable, and globally competitive power semiconductor production in China.
Enabling the Industry: Automotive and Industrial Power Electronics
Dr. William’s influence extends across the broader power electronics ecosystem. He has provided in-depth technical guidance to leading enterprises such as BYD, Resources, and Sino, supporting power module development, production line deployment, and automotive power electronics innovation.
His work has directly contributed to strengthening China’s supply chain capabilities in electric vehicles (EVs), industrial motor drives, and energy-efficient power conversion systems, accelerating the adoption of high-performance domestic power semiconductor solutions.
Building the Future: Strategic Collaboration with SHYSEMI
With decades of industrial insight, Dr. William founded Guangdong Huixin Semiconductor Co., Ltd., focusing on next-generation power semiconductor technologies and advanced power module design. Huixin Semiconductor later formed a strategic partnership with SHYSEMI, jointly establishing Shenzhen Huixin Semiconductor Co., Ltd.
Through close collaboration, both companies integrate expertise in power device design, process innovation, and market-driven applications, accelerating the development of high-efficiency, high-reliability power modules for industrial, automotive, and energy markets.
Why Leadership Matters in Power Semiconductor Innovation
The evolution of the power semiconductor industry is not driven by technology alone—it requires leaders who understand devices, manufacturing, standards, and ecosystems. Dr. William’s career reflects this full-spectrum expertise, from global R&D and original invention to mass production and industry-wide collaboration.
As demand continues to grow for IPMs, HVICs, IGBT modules, and advanced power semiconductor solutions, his work remains a key force shaping China’s competitiveness in the global power electronics landscape.
