SEMIPOWER develops WBG power module technologies for high-efficiency applications

By AI, Created 8:25 AM UTC, May 21, 2026, /AGP/ – SEMIPOWER in Busan is advancing next-generation power semiconductor modules built around silicon carbide and gallium nitride. The work targets electric vehicles, renewable energy, industrial automation and other systems where higher efficiency and better thermal performance matter.

Why it matters: - Wide bandgap power modules are becoming more important as EVs, renewable energy systems and industrial equipment demand more efficient power conversion. - SiC and GaN can support higher switching frequencies, better thermal performance and lower energy loss in high-voltage and high-temperature environments. - SEMIPOWER’s work sits in a market where demand for advanced power modules is expected to grow as electrification and energy-efficiency rules expand.

What happened: - SEMIPOWER, a South Korea-based semiconductor company, is developing next-generation power semiconductor module solutions centered on silicon carbide and gallium nitride. - The company focuses on power module design, thermal management and customized packaging technologies for high-efficiency power conversion applications. - SEMIPOWER is headquartered in Busan and runs research and development activities for custom and standard power module solutions for industrial and energy applications.

The details: - SEMIPOWER’s development work centers on power module packaging and integration technologies aimed at improving power density and heat dissipation. - The company uses Ag sintering, or silver sintering, die-attach processes to improve thermal conductivity and operational reliability in demanding applications. - SEMIPOWER’s engineering approach includes low-inductance module structures and internal circuit configurations tailored to customer requirements. - The company says its solutions can be adapted through changes in internal circuitry, current specifications and package structures depending on application needs. - SEMIPOWER is also working on Ceramic in Board technologies that combine features of conventional FR4 boards and ceramic substrates. - The CiB approach is intended to support high thermal conductivity and insulation performance in compact power electronics systems. - Power semiconductor modules are used in EV powertrains, renewable energy inverters, industrial motor drives, energy storage systems and high-efficiency power conversion equipment. - The company provided its website as more information.

Between the lines: - SEMIPOWER is positioning itself around the packaging, thermal and integration challenges that often determine whether SiC and GaN designs can scale in real products. - The emphasis on customized structures suggests the company is aiming at application-specific customers rather than one-size-fits-all modules. - Analyst expectations for continued market growth point to sustained demand for suppliers that can improve efficiency and reliability at higher power densities.

What’s next: - SEMIPOWER is likely to keep refining module structures, packaging methods and thermal management features for industrial and energy customers. - Broader adoption of electrification and efficiency regulations should keep pressure on suppliers to deliver smaller, cooler and more efficient power modules. - The company’s Busan R&D base suggests ongoing development of both custom and standard offerings for changing application requirements.
