Abstract
With the growing global energy demand and the rapid development of power electronics technology, efficient and reliable power conversion equipment has become the core demand of modern industrial systems. As an important part of the field of power electronics, inverter plays a key role in motor drive, energy management and other aspects. This study takes the application of new power electronic devices in frequency converter to explore its potential to optimize system performance. By comparing the characteristics of traditional silicon-based devices with new wide-band semiconductors (such as SiC and GaN), the combination of simulation analysis and experimental verification is used to evaluate the performance of the new devices under high-frequency switching, low loss and high-temperature operating conditions. The results show that the frequency converter based on wide band semiconductor has significant advantages in efficiency improvement, volume reduction and dynamic response improvement. Especially in application scenarios with high power density and extreme environments, the new devices show a performance level beyond the reach of traditional technologies.
