Model-Based Medium-Voltage Induction Machine Insulation Material Characterization, Arshiah Yusuf Mirza
Master's Theses
The voltage and frequency handling capability of power converter modules have tremendously increased with the penetration of wide-band-gap (WBG) semiconductor technology in power electronics. However, very little is known about the effect of the high-voltage high-frequency transients exerted by WBG power electronics on insulation materials. This thesis investigates the effect of high-voltage, high-frequency transients on aging and breakdown characteristics of insulation materials. The aim of this research was to analyze this breakdown and develop the behavioral model of the breakdown time when such insulation materials are used in inverter-fed medium-voltage induction machines. As a part of this research, a series …
