Electrolytic Capacitorless Pulsating DC Link Three-Phase Inverter for Low Voltage Battery EVs
Presenter: Akshay Kumar Rathore, Singapore Institute of Technology, Singapore
Date: Tuesday, August 23, 2022, 10:00 AM EDT
Abstract: Sinusoidal Pulse Width Modulation (SPWM) and space vector modulation (SVM) have been widely adopted for three-phase sine AC output from a fixed dc-link if the dc-link voltage is much higher than desired three-phase output. However, if the source/dc-link voltage is lower than the load voltage, then frond-end dc/dc converters becomes necessary leading to the design of the multistage power conversion system. This is the case with the 48 V electrical vehicles (EVs). To implement the propulsion drive system with existing SVM or carrier-based modulation, a large costly unreliable electrolytic capacitor is employed to develop a high voltage intermediate dc link. Novel Single-reference-Six-Pulse Modulation (SRSPM) eliminates the dc-link electrolytic capacitor allowing pulsating dc-link voltage waveform at the inverter input. It substantially reduces the cost, size, and weight and improves the reliability of the system. This novel SRSPM is simple and results in a saving of 87% switching losses. The concept has been experimentally demonstrated with closed-loop control to achieve 97% efficiency in the lab.

Wireless Charging of EVs
Presenter: Dr. Suvendu Samanta, Indian Institute of Technology Kanpur, UP, India
Date: Tuesday, September 27, 2022, 10:00 AM EDT
Abstract: Wireless power transfer (WPT) technology promises a very convenient, reliable, and safe way of transferring power wirelessly. The applications of this technology are charging electric vehicles (EV), electronic gadgets, implants, and powering LED lighting and data centers. This seminar's first part will address WPT technology's basics, including classification, design, and control. The later part of this seminar will focus on WPT topologies with the current-source inverter (CSI). The existing research on WPT is mainly based on power converters derived from voltage-source inverter (VSI) topologies. In contrast, the feasibility of the CSI has received limited attention. Considering certain limitations of WPT with voltage-fed converters, a concept study and feasibility analysis of different current-fed power electronic converters for WPT systems will be presented.
