On July 5, on the occasion of the 10th anniversary of Shanghai Electric Fuji Electric Power Technology Co., Ltd. (hereinafter referred to as "Shanghai Electric Fuji"), the world's largest single capacity (10KV 50MVA) voltage-source water-cooled inverter successfully rolled off the production line and a product launch ceremony was held. Shiro Kondo, Representative Director and President of Fuji Electric, Jin Xiaolong, Party Committee Member and Vice President of Shanghai Electric, and other executives attended the event and witnessed this milestone.

The development of this product took 15 months, during which the R&D team overcame multiple technical challenges, built a high-power electric drive integrated technology platform, and launched the innovative water-cooled inverter and electric drive system solution featuring high frequency, high efficiency, high reliability, high performance, intelligence and integration. This inverter adopts a multi-level voltage source unit series connection. The internal power unit adopts modular design, which consists of rectifier module, capacitor module and inverter module, and the modules are electrically connected by stacked busbar. With a multi-pipe parallel design for heat dissipation, the maximum capacity of a single unit can reach 50 MVA (under the condition of 10 kV voltage).

The world's largest single capacity (10KV 50MVA) voltage-source water-cooled inverter has two unique benefits. First, its excellent energy-saving performance minimizes full-cycle investment costs, thus bringing great economic value. Second, it strongly supports the realization of the "dual carbon" goal and promotes the localization of key ultra-high power equipment in the fields of new energy air storage, chemicals, gas-to-electricity conversion and water conservancy, which have significant social value. This innovative achievement is not only a major milestone in the research, development and expansion of the product line, but also a strong demonstration of the company's leading position in the field of inverters in China.

As a model of outstanding cooperation between Shanghai Electric and Fuji Electric, Shanghai Electric Fuji is committed to the continuous development of inverters, helping Shanghai Electric strengthen an industrial drive system of “motor + inverter + control”. It also invests in new energy PCS, helping Shanghai Electric build a "battery+” new energy storage system. With the profound brand heritage, great technical strength and strong market influence of the two parent companies, Shanghai Electric Fuji will continue to pursue excellence, innovation and breakthroughs, and provide high-quality, high-performance power transmission products and system engineering solutions to customers around the world.
