基于宽带隙（WBG）器件的电力电子变换器比基于硅的变换器更高效且重量更轻。WBG器件是许多电机驱动应用和新型紧凑高效电机的一项使能技术。本文综述了WBG器件在交流电机驱动中的潜在应用和进展。介绍了使用WBG器件的工业电机驱动产品，并强调了其优点。本文还讨论了实现电机驱动器中WBG器件全部潜力的技术挑战、转换器设计考虑因素和设计权衡。在高开关频率和诸如高dv/dt和电磁干扰的其它问题之间存在折衷。讨论了高dv/dt引起的高共模电流、轴承和绝缘损坏问题以及WBG器件的可靠性问题。
Wide bandgap (WBG) device-based power electronics converters are more efficient and lightweight than silicon-based converters. WBG devices are an enabling technology for many motor drive applications and new classes of compact and efficient motors. This paper reviews the potential applications and advances enabled by WBG devices in ac motor drives. Industrial motor drive products using WBG devices are reviewed, and the benefits are highlighted. This paper also discusses the technical challenges, converter design considerations, and design tradeoffs in realizing the full potential of WBG devices in motor drives. There is a tradeoff between high switching frequency and other issues such as high dv/dt and electromagnetic interference. The problems of high common mode currents and bearing and insulation damage, which are caused by high dv/dt, and the reliability of WBG devices are discussed.
