Analysis and Design Considerations of a Contactless Magnetic Plug for Charging Electric Vehicles Directly From the Medium-Voltage DC Grid With Arc Flash Mitigation

Authors: Richard B. Beddingfield, Suvendu Samanta, Mark S. Nations, Isaac Wong, Paul R. Ohodnicki Jr., and Subhashish Bhattacharya
Extended Abstract:

High power electric interconnects are challenging to create safely. Furthermore, disconnecting them while a load is energized can often lead to a localized arc within the plug as the …

Frequency-Domain Modeling of Dual-Active-Bridge Converter Based on Harmonic Balance Approach

Authors: Sayandev Ghosh, Dhiman Das, Bhim Singh, Sindhu Janardhanan, Sukumar Mishra
Extended Abstract:

The dual active bridge (DAB) converter contains both AC and DC states. Hence, state space average modeling of DAB is intricate. In the literature, several models of DAB have been developed to reconstruct the …

An Artificial Intelligence Approach for Real-Time Tuning of Weighting Factors in FCS-MPC for Power Converters

Authors: Sergio Vazquez; Daniel L. Marino; Eduardo Zafra; Maria Dolores Valdes Pena; Juan J. Rodriguez-Andina; Leopoldo Garcia Franquelo; Milos Manic
Extended Abstract:
In this paper a finite control set model predictive control is used to track a current reference in a power converter connected to an RL load. An artificial intelligence (AI) approach is …

A Resonant Frequency Tracking Technique For LLC Converters Based DC Transformers

Authors: Yuqi Wei, Quanming Luo, Alan Mantooth
Extended Abstract:
Large circulating current and reactive power exist for the LLC / CLLC converter in the case that f s < f r , where f s is the switching frequency and f r is the resonant frequency; on the other hand, in the scenario of f s > f r …

Towards Grid of Microgrids: Seamless Transition between Grid-Connected and Islanded Modes of Operation

Authors: Silvanus D’silva, Mohammad Shadmand, Sertac Bayhan, Haitham Abu-Rub
Extended Abstract:
With the ever-increasing number of blackouts in distribution systems arising from a variety of natural and manmade disasters, the frequent and necessary isolation/reconnection of loads without power deviations/fluctuations has become an important issue. Grid of microgrids (MGs) is …
