Title:Measurement Setup Consideration and Implementation for Inductively Coupled Online Impedance Extraction

Authors:Zhenyu Zhao

Abstract:This thesis is organized as follows: Chapter 1 introduces the background, motivation, objectives, and contributions of this thesis. Chapter 2 presents a review of existing online impedance extraction approaches. Chapter 3 proposes the improved measurement setup of the inductive coupling approach and introduces the theory behind time-variant online impedance extraction. Chapter 4 develops a three-term calibration technique for the proposed measurement setup to deembed the effect of the probe-to-probe coupling between the inductive probes with the objective to improve the accuracy of online impedance extraction. Chapter 5 discusses the additional measurement setup consideration in industrial applications where significant electrical noise and power surges are present. Chapter 6 discusses and demonstrates the application of the inductive coupling approach in online detection of the incipient stator faults in the inverter-fed induction motor. Chapter 7 further extends the application of this approach for non-intrusive extraction of the voltage-dependent capacitances of the silicon carbide (SiC) power metal-oxide-semiconductor field-effect transistor (MOSFET). Finally, Chapter 8 concludes this thesis and proposes future works that are worth exploring.
