Real-Time Monitoring of Temperature Rises of Energized Transformer Cores With Distributed Optical Fiber Sensors
Ping Lu,Michael P. Buric,Kevin Byerly,Seung Ryul Moon,M. Nazmunnahar,S. Simizu,Alex Leary,Richard Beddingfield,Chenhu Sun,Paul Zandhuis,Michael E. McHenry,Paul R. Ohodnicki +11 more
TL;DR: In this paper, the authors investigate thermal response of a standard telecom fiber instrumented on compact transformer cores by using an optical frequency-domain reflectometry scheme and show the tradeoffs between spatial resolution and temperature measurement accuracy.
Journal ArticleDOI
Metal Amorphous Nanocomposite (MANC) Alloy Cores with Spatially Tuned Permeability for Advanced Power Magnetics Applications
Kevin Byerly,Paul R. Ohodnicki,S. R. Moon,S. R. Moon,Alex Leary,V. Keylin,Michael E. McHenry,S. Simizu,Richard Beddingfield,Yang Yu,G. Feichter,Ronald D. Noebe,R. R. Bowman,Subhashish Bhattacharya +13 more
TL;DR: In this paper, the concept of spatially varying the permeability within a given component for optimization of performance by using the strain annealing process is demonstrated experimentally through the smoothing of the flux profile from the inner to outer core radius achieved by a monotonic variation in tension during the strain-annealing procedure.
Journal ArticleDOI
Thermal profile shaping and loss impacts of strain annealing on magnetic ribbon cores
Richard Beddingfield,Subhashish Bhattacharya,Kevin Byerly,S. Simizu,Alex Leary,Michael E. McHenry,Paul R. Ohodnicki +6 more
TL;DR: The use of the advanced manufacturing technique of strain annealing for nanocomposite magnetic ribbons enables control of relative permeabilities and spatially dependent permeability profiles as discussed by the authors.
Proceedings ArticleDOI
Shielding of Leakage Flux Induced Losses in High Power, Medium Frequency Transformers
TL;DR: In this paper, a method of using a mix of materials to manage and direct the leakage flux through paths that are more efficient is presented, which enables deliberate tuning and design of the series inductance.
Proceedings ArticleDOI
Large Scale Grid Integration of Photovoltaic and Energy Storage Systems Using Triple Port Dual Active Bridge Converter Modules
Viju Nair R,Srinivas Gulur,Ritwik Chattopadhyay,Richard Beddingfield,Shashank Mathur,Subhashish Bhattacharya,Ghanshyamsinh Gohil,Paul R. Ohodnicki +7 more
TL;DR: This paper shows that the triple port DAB modules along with the inverter is a viable option for large scale PV-ESS grid integration and investigates various operating and control modes.
