Focus on wide-bandgap power semiconductor devices design and Marketing

Represented by silicon carbide and gallium nitride, the third-generation semiconductor materials are characterized by large forbidden band gap, high breakdown field strength, high thermal conductivity, high electron saturation rate and strong radiation resistance. Compared with traditional silicon-based power semiconductor devices, power semiconductor devices based on silicon carbide and gallium nitride have significant advantages such as low on-resistance, low switching loss, high operating junction temperature, and high thermal conductivity. Therefore, the power electronic converters using SiC-based power semiconductor devices and GaN-based power semiconductor devices can significantly increase the switching frequency and reduce the size of heat sinks, energy storage elements and filters, so as to achieve higher conversion efficiency and power density. Meanwhile, SiC-based power semiconductor devices and GaN-based power semiconductor devices are gradually replacing traditional silicon-based power semiconductor devices, bringing a far-reaching change to the power electronic converter industry. PN Junction Semiconductor focuses on the design and promotion of third-generation semiconductors, having profound technology accumulation and comprehensive industrial chain advantages.
