Abstract:

Wide-bandgap (WBG) power devices are poised to have a major impact on future machine drives.  The objective of this tutorial is to assistdrive design engineers to prepare for this transition.The impact of introducing WBG switches into hard-switched voltage-source inverters (VSI) will highlight the challenges associated with drop-in replacement strategies.  Advanced inverter bridge-leg topologies that are well-suited to WBG switches will be presented, as well as opportunities for the re-emergence of current-source inverters (CSIs).  The tutorial will address practical challenges associated with designing WBG-based inverters and conclude with a discussion of current and future applications of WBG-based motor drives.
