Biography
SVSV Prabhu Deva Kumar received the B.Tech. degree in electronics and communication engineering from ITM University, Gwalior, India, in 2018, the M.S. degree in electrical engineering from Pusan National University, Busan, South Korea, in 2020, and the M.A.Sc. degree in electrical and computer engineering from McMaster University, Hamilton, Ontario, Canada, in 2025. He is currently pursuing the Ph.D. degree in electronics and communication engineering at ITM University, Gwalior, India, and the M.B.A. degree in finance from Andhra University, Andhra Pradesh, India.
He is currently a Systems Designer (R&D Team Lead) at Verdyn Inc., Toronto, Canada, where he leads the development of advanced DC fast-charging systems for electric vehicles and microgrid integration solutions. Previously, he served as a Sessional Faculty and Teaching Assistant at McMaster University, Hamilton, Ontario, Canada (2023-2025), a Senior Researcher in R&D BMS at NANOINTECH Co., Ltd., Republic of Korea (2022-2023), and an Electrical Researcher in R&D Smart Grid at JoongAng Control Co., Ltd., Republic of Korea (2020-2022). He has authored multiple research articles in peer-reviewed journals and conferences, and has contributed chapters to Hybrid Intelligence for Smart Grid Systems (Florida, USA: CRC Press Taylor and Francis Group, 2021). His current research interests include power converter topologies for inverters and DC converters, battery management systems, EV charging infrastructure, and smart grid technologies.
Mr. Kumar has filed multiple patents related to EV charging technologies in Canada, and India, including a universal DC fast charger topology and wide voltage range bidirectional charging modules.

As EV fast charging infrastructure has developed rapidly, electromagnetic compatibility (EMC) problems with DC-DC high-frequency converters have become more acute. In particular, multi-source multi-level active bridge (MS-ML-DAB) converters operating over a wide range of output voltages experience significant electromagnetic interference (EMI) due to rapid switching transitions and parasitic components. This study systematically analysed the electromagnetic interference (EMI) generated by the common mode (CM) and differential mode (DM) of the MS-ML-DAB converter for EV DC fast charging systems. A parasitic converter model is proposed to precisely identify the major noise processes in the EMI. Using FCC Class B emission-guided and impedance-based design concepts, the multi-stage EMI filter of the type π is analytically constructed for both input and output ports. The recommended filter shall provide impedance matching, adequate damping and stability in the event of significant voltage and current fluctuations. PSIM based simulations show significant noise abatement of DM and CM in the frequency range 150kHz to 30MHz in both working modes, confirming compliance with FCC Class B standards. This technique offers a practical and scalable solution to mitigate the EMF in high-power EV chargers.
