Core Viewpoint - The company has successfully developed a new "medium-frequency isolation single-phase topology" technology in collaboration with Tsinghua University, which reduces both core loss and switching loss, breaking through the efficiency ceiling of traditional high-frequency topologies. This represents a significant leap from "application optimization" to "underlying architecture innovation" in SST technology [1]. Group 1 - The company has obtained multiple software and hardware invention patents in the SST technology field, including the medium-frequency isolation technology [1]. - The company aims to maintain its technological leadership and strengthen its patent barriers to create a robust competitive advantage [1].
