Abstract
With the advent of industry 4.0 era, the importance of efficient motor drive system in the field of intelligent manufacturing and energy saving and emission reduction is becoming increasingly prominent. This paper presents a new solution based on wide band semiconductor materials for the efficiency bottleneck and reliability problems in motor drive applications. By adopting third-generation semiconductor materials such as silicon carbide and gallium nitride, combined with innovative device structure and packaging technology, the switching frequency and power density of the device have been significantly improved. The combination of theoretical analysis, simulation modeling and experimental verification is used to investigate the dynamic characteristics and thermal management performance of the new device under different working conditions. The experimental results show that compared with the traditional silicon-based devices, the switching loss of the new power electronic devices is reduced by 40%, and the overall efficiency of the system is improved by 5-8%. At the same time, by optimizing the drive circuit design and the electromagnetic compatibility processing, the electromagnetic interference problem caused by the high frequency switch is effectively solved.
