Taisic unveils p-type SiC substrate for ultra-high-voltage grid, rail applications

Taisic's unveiling of p-type SiC substrates marks a significant stride for China in high-voltage power electronics. This development directly impacts the upstream supply chain of IGBTs and SiC power devices, particularly for smart grids and rail transit applications. The move accelerates domestic industry alignment, pushing manufacturers to intensify investments in SiC end-to-end capabilities. From a compliance standpoint, it may prompt stricter export controls from Western nations, heightening supply chain risks. Competitors such as China Resources Micro and BYD are likely to accelerate their own SiC substrate R&D efforts. Over the next 12–24 months, as high-voltage SiC adoption grows, the industry will see rapid technological maturation and cost reduction, signaling a potential shift toward domestic self-reliance in high-voltage power electronics.
