Nexfi Technology

NexFi Technology Inc. is a Japanese startup established in June 2021, positioning itself as a specialized developer and manufacturer of high-voltage equipment. The company spun out from a division of Fukushima SiC Applied Engineering, Inc. and was founded by Takashi Nakamura, who now serves as President and CEO. Nakamura's journey includes a significant tenure at ROHM Co., Ltd., where he served as the Center Director for the New Materials and Devices R&D Center, after earning a Ph.D. in Engineering from Kyoto University. This extensive background in materials and device research directly informs NexFi's focus on leveraging next-generation silicon carbide (SiC) power devices.

Based in Osaka, with its headquarters and development hub located within Osaka University, NexFi Technology operates at the intersection of academic research and industrial application. The company's business model centers on the design, production, and sale of specialized high-voltage components to other businesses. Its core revenue is generated from these sales, targeting clients in sectors that require advanced power control for industrial development and environmental problem-solving. By capitalizing on the superior performance of SiC power devices, NexFi aims to become an indispensable partner for users of high-voltage special power supplies.

The company's product portfolio is divided into two main categories. First, it offers high-voltage DC power supplies that utilize SiC inverters and SiC Cockcroft-Walton multipliers, designed for applications ranging from 5 kV to 300 kV. These power supplies boast high conversion efficiency and a significantly smaller volume compared to traditional alternatives. The second product line consists of high-voltage switching modules. These modules employ series-connected SiC MOSFETs with proprietary voltage balancing methods to achieve switching capabilities beyond 50 kV. They are engineered for demanding applications such as high-current pulse generation, high-frequency hard switching, and DC circuit breaking without an arc. A notable application of its technology, in a joint project with Osaka University, has been the successful high-efficiency decomposition of PFAS chemicals using a newly developed high-frequency pulse generator.
