Re-emergence of Current Source Inverters using Wide Bandgap Devices and Comparison with Voltage Source Inverters

Presenter: Bulent Sarlioglu, Ph.D., Professor, University of Wisconsin-Madison, USA, IEEE Distinguished Lecturer


Wide-bandgap (WBG) power devices are about to have a significant impact on future machine drives.  In this lecture, Dr. Sarlioglu will present the most recent research results for current source inverters (CSI) and compare the CSI with voltage source inverter.  Current source inverters feature interesting characteristics, i.e., almost sinusoidal output voltage, reduced EMI/EMC and bearing current issue, no-dc link capacitor, high-temperature capability. With the high switching capability of WBG devices, the dc-link inductor of the CSI can be significantly reduced and opens the door for competition with VSI.   In the second part of his talk, Dr. Sarlioglu will present high efficiency and high power density integrated motor drive concepts using wide-bandgap (WBG) power devices. Integrated motor drives have various benefits, including eliminating cable between the motor and power electronics, reducing the EMI/EMC emissions, and potential joint cooling of the motor and power electronics.  The lecture will include practical challenges associated with designing WBG-based inverters and conclude with a discussion of current and future applications of WBG-based motor drives.
