The "control center" of power systems, specializing in efficient energy conversion and intelligent control in high-voltage and high-current scenarios. Leveraging wide-bandgap materials such as SiC (silicon carbide) and GaN (gallium nitride), it breaks through the limitations of silicon-based technology, achieving ultra-low loss and high-frequency switching performance. Widely used in renewable energy generation, electric vehicle powertrains, industrial frequency conversion, and smart grids. Its high-temperature resistance and radiation tolerance ensure stable operation in extreme environments. With the deepening of the energy revolution, modular integration and smart sensing technologies are rapidly advancing, continuously supporting carbon neutrality goals and serving as foundational components in the era of power electronics.
