Catalyzed by the demand for AI computing power and electricity, SST (Solid-State Transformer) technology is quietly emerging as a new trend in the power equipment sector. Reporters noted that recently, multiple publicly listed firms have announced their entry into the SST arena. As a medium- and high-voltage directly connected power electronic device, SST differs from the electromagnetic induction path of traditional power-frequency transformers based on "iron cores + windings." Instead, it utilizes power semiconductor devices to directly build a high-frequency "power direct bridge" between the medium-voltage side and the DC low-voltage side. This architecture eliminates bulky power-frequency transformers, multi-stage rectifiers, and filtering devices, condensing complex power transformation processes into a compact form. Since the beginning of this year, the sustained boom in artificial intelligence data centers (AIDC) has thrust SST, a highly integrated power electronic solution, into the spotlight.
