   Current Sensor-free Transfer Window Alignment for Current Transformer Energy Harvesting
By Tim MCRAE [View]
[Download]

Abstract: An energy harvesting circuit has been developed to power an IoT network which measures energy consumption at the outlet level. This work integrates the rectification and down-stream voltage regulation stages, allowing the capacitor voltage to be used to measure current. An experimental prototype is developed to demonstrate the proposed algorithm.

   Influence of Controller Parameters on Open-Circuit Fault Localization Time in Full-Bridge Modular Multilevel Converter
By Miad AHMADI, Aditya SHEKHAR, Pavol BAUER [View]
[Download]

Abstract: Modular Multilevel Converters (MMCs) have gained significant attention in academia and industry due to their versatility in various applications. MMCs are known for their high efficiency, superior harmonic performance, scalability, and modularity. However, their complexity in control, reliability issues, and many components present challenges. Numerous submodule (SM) configurations have been proposed in the literature, each with advantages and disadvantages. The full-bridge (FB) configuration stands out for its robustness against DC link faults. Nevertheless, the FB SM containing four switches is susceptible to open-circuit failures (OCF). Few studies have explored such failures in FB MMCs. This paper investigates the impact of controller parameters on fault localization time in the event of an OCF in any of the four switches. The study uses two different modulation strategies, and the results are validated through simulation.

   Parametric Life Cycle Assessment (LCA) of Power Modules
By Li FANG, Lucas RIONDET, Maud RIO, Pierre LEFRANC, Fatimata-Fatim DIARRASSOUBA, Jean-Christophe CREBIER [View]
[Download]

Abstract: Power Electronics is a key factor in the electrification of our modern society. In the attempt of massive decarbonation, this fast-growing industry is going to put pressure on the environment. Life Cycle Assessment is used to identify the main impacts of products and services. The paper presents an open-source method to carry on a parametric LCA of power modules to help power electronics designers and engineers assess the environmental impacts of such devices when used in power converters. After recalling how is derived the open access LCI of a type of power modules, the method to implement Parametric LCA for this kind of device is introduced. It is then applied on a specific case study for automotive applications and main LCA results are provided to illustrate the method. The last section is dedicated to introduce several perspectives and applications of Parametric LCA to support ecodesign.
