Mitsubishi Electric Corporation has signed a basic agreement with Taiwan’s Industrial Technology Research Institute (ITRI), in collaboration with Mitsubishi Electric Taiwan Co., Ltd., to jointly develop high-voltage, high-current power conversion systems (PCSs) that use advanced power semiconductors for renewable energy applications such as solar and wind power.
Under this partnership, Mitsubishi Electric will provide its high-efficiency power semiconductor modules, while Mitsubishi Electric Taiwan contributes its market expertise. ITRI will apply its system integration and power conversion technologies to create a megawatt-class PCS prototype for demonstration testing. The collaboration aims to advance technology that efficiently converts electricity from renewable sources while supporting the growth of Taiwan’s renewable energy ecosystem.
Mitsubishi Electric and its Taiwan subsidiary plan to share design insights and test results with PCS manufacturers, helping them optimize their products using Mitsubishi Electric’s power semiconductor modules. ITRI will also offer related design documentation and data to support local industry development. Through this effort, both organizations aim to contribute to the global transition toward low-carbon, sustainable energy systems.
As renewable energy generation expands worldwide, demand for large-scale PCSs capable of converting electricity between direct current (DC) and alternating current (AC) continues to grow—particularly for megawatt-class systems used in large solar or wind installations.
Mitsubishi Electric brings decades of experience in producing reliable, high-voltage, high-current semiconductor modules used in renewable energy generation, energy storage, and transmission. Known for their durability and stable performance in challenging environments, these modules are widely adopted across global markets.
ITRI, a leading research institute focused on the circular economy, low-carbon manufacturing, and renewable technologies, has extensive expertise in high-voltage and high-current power systems. It has played a key role in advancing Taiwan’s technology industries through innovation and collaboration with local companies.
Jwu-Sheng Hu, Executive Vice President at ITRI, said that the partnership represents a major step forward in Taiwan’s energy transition. He noted that as power systems evolve to accommodate renewable sources, stability and efficiency are becoming increasingly important. The collaboration with Mitsubishi Electric, Hu said, will combine ITRI’s system integration strengths with Mitsubishi Electric’s semiconductor expertise to improve green energy integration and strengthen Taiwan’s role in the global clean energy supply chain.
Masayoshi Takemi, Executive Officer and Group President of the Semiconductor & Device Group at Mitsubishi Electric, described the agreement as an important milestone for advancing renewable energy adoption. He said the partnership will help accelerate the development of megawatt-class power conversion systems using Mitsubishi Electric’s power semiconductor technologies. Takemi added that Mitsubishi Electric remains committed to supporting a sustainable society through solutions that balance environmental responsibility with business growth.
