General and Unified Model of the Power Flow Problem in Multiterminal AC/DC Networks
Mario Paolone, Willem Lambrichts
This paper proposes a generic and unified model of the power flow (PF) problem for multiterminal hybrid AC/DC networks. The proposed model is an extension of the standard AC-PF. The DC network is treated as an AC one and, in addition to the Slack, PV and P ...
2024A modular multiple frequency inductive link to wirelessly power multiple miniaturized implants
Sandro Carrara, Diego Ghezzi, Gian Luca Barbruni
A modular multiple frequency coils inductive link system to wirelessly provide power for at least a medical implant at an output of a receiving coil, whereby the receiving coil is configured to be implanted in an organism. The modular multiple frequency co ...
2024Ripple Voltage and Loss Reduction of Single-Phase ISOP SST by Eliminating the Second Harmonic Current in LLC Converters
Drazen Dujic, Andrea Cervone, Tianyu Wei
In two-stage solid-state transformers with input-series output-parallel structure, the LLC converter operating at a fixed switching frequency is a common choice for the isolated DC/DC conversion stage because it can provide a high efficiency and a fixed vo ...
2024Stability Analysis of Second-Order Harmonic Active Filters for Input-Series/Output- Parallel Solid State Transformers
Drazen Dujic, Andrea Cervone, Tianyu Wei
Solid-State Transformers with Input-Series/Output- Parallel configuration offer a convenient solution for AC/DC power conversion, thanks to their modularity, scalability and flexibility. However, as known, they are affected by a second-order harmonic rippl ...
2024Reversible photo-electrochemical device for solar hydrogen and power generation
Sophia Haussener, Saurabh Yuvraj Tembhurne, Alexandre Dominique M. Cattry, Matthieu Jonin, Mahendra Patel
A reversible photo-electrochemical device operating under concentrated irradiation could offer a stand-alone solution for producing solar fuel (in photo-driven electrolysis mode) and power (in fuel cell mode). This strategy would present the advantage of h ...
2024Integrated Wireless Power, Data Communication, and Thermal Sensing System for Autonomous Multisite Brain Implants
Implanted medical devices (IMDs) have been widely developed to support the monitoring and recording of biological data inside the body or brain. Wirelessly powered IMDs, a subset of implantable electronics, have been proposed to eliminate the limitations r ...
EPFL2024Stability Analysis of Input-Series/Output-Parallel Solid-State Transformers Equipped with Second-Order Harmonic Active Power Filters
Drazen Dujic, Andrea Cervone, Tianyu Wei
Solid-State Transformers with Input-Series/Output-Parallel configuration offer a convenient solution for AC/DC conversion due to their scalability and modularity. In this configuration, each module experiences a second-order harmonic ripple caused by local ...
2024Active Power Decoupling for Single-Phase Input-Series-Output-Parallel Solid-State Transformers
Drazen Dujic, Andrea Cervone, Tianyu Wei
Solid-state transformers with input-series outputparallel structures are being considered for a variety of applications requiring MVAC to LVDC conversion. Due to the singlephase AC/DC conversion at the input side, all floating cells of the solid-state tran ...
2024Energy-Efficient Frequency Selection Method for Bio-Signal Acquisition in AI/ML Wearables
David Atienza Alonso, Miguel Peon Quiros, José Angel Miranda Calero, Hossein Taji
In wearable sensors, energy efficiency is crucial, particularly during phases where devices are not processing, but rather acquiring biosignals for subsequent analysis. This study focuses on improving the power consumption of wearables during these acquisi ...
