Windsun Science Technology Co.,Ltd. (688663.SH) has announced the successful completion of its independently developed next-generation solid-state transformer (SST) prototype. The SST, also known as a power electronic transformer, is regarded as an "energy router" for new power systems. It integrates voltage transformation, electrical isolation, bidirectional power control, power quality management, and intelligent dispatch into a single unit. This equipment is essential for integrating high proportions of renewable energy, hybrid AC/DC distribution networks, and ensuring highly reliable power supply for critical loads. The completion of this new SST prototype marks a milestone in the company's core technology research and development. Moving forward, the company plans to continue advancing the engineering iteration and commercial application of SST products while expanding its related product portfolio.
