Item Challenges in Developing Hardware-In-Loop Model of Cage Induction Motor with Eccentricity Fault(IEEE Computer Society help@computer.org, 2018) Ilamparithi, T.; Rangachar, B.; Rangineedi, T.; Nagendrappa, H.In this paper, an attempt is made to develop a MATLAB based Hardware-In-Loop compatible model of a three phase cage induction motor with a provision to accommodate eccentricity fault. The major benefits of the attempted work include compatibility with commercially available real-time simulators, facilitation of testing motor control units of electric vehicles when the motor is subjected to eccentricity fault, and ability to simulate in real-time varying severities of eccentricity fault. Modeling of the eccentricity fault is made by using the widely adopted modified winding function approach. Real-time simulation of the developed model is attempted by building a MATLAB model that utilizes pre-computed inductances for real-time execution. Finally, the major challenges encountered in this attempt are presented and discussed to pave way for further research. © 2018 IEEE.Item Comparative Study on Efficiency and Output Voltage Regulation in Dual-Active Bridge Converter with SPS and TPS Modulation under Input Voltage Variations(Institute of Electrical and Electronics Engineers Inc., 2024) Ur Rehman, M.B.; Ilamparithi, T.; Nagendrappa, H.The comprehensive performance characteristics of two prominent modulation techniques on Dual-Active Bridge (DAB) converter: Single Phase Shift (SPS) and Triple Phase Shift (TPS) is presented in this paper. The DAB converter topology is a promising architecture for its high-efficiency, bidirectional power conversion, galvanic isolation and flexible gating schemes. The primary objective is to evaluate the effectiveness of modulation techniques on output voltage regulation under varying input voltage conditions. Phase displacement patterns and their correlation with the varying input voltage are illustrated graphically along with the detailed results. A comprehensive design analysis is developed, followed by the detailed simulation results is showcased for a 1 kW converter in boost mode of operation. This study highlights the insights for the selection and optimization of modulation strategies for DAB converter in applications demanding precise output voltage regulation and high efficiency. © 2024 IEEE.
