SFBAC PELS WEBSITE LINK: http://ewh.ieee.org/r6/scv/pels/index.html Abstract: In photovoltaic (PV) systems connected to the AC power grid, traditional approaches employing series-connected PV panels with a single central converter often suffer from reduced efficiency and reliability due to partial shading or mismatch of PV cell characteristics. To address these challenges, the concept of differential power processing (DPP) converters has emerged, enabling independent maximum power point tracking (MPPT) of each PV panel while mitigating power loss under mismatched conditions. Various DPP system configurations are introduced and their advantages and trade-offs discussed. Additionally, recent research comparing bidirectional flyback and split-inductor boost converter topologies for PV-to-bus DPP systems is presented. Experimental results demonstrate a converter efficiency improvement of 14.7% over traditional flyback converters, offering promising avenues for enhancing the efficiency and reliability of PV systems. About the Speaker: [] Dr. Katherine A. Kim received the B.S. degree in Electrical and Computer Engineering (ECE) from the Franklin W. Olin College of Engineering in 2007. She received the M.S. degree and Ph.D. degree in ECE from the University of Illinois at Urbana-Champaign in 2011 and 2014, respectively. She was an Assistant Professor of ECE at Ulsan National Institute of Science and Technology (UNIST), Ulsan, South Korea, from 2014-2018. Since 2019, she has been an Associate Professor of Electrical Engineering at National Taiwan University, Taipei, Taiwan. She received the IEEE PELS Award for Achievements in Power Electronics Education in 2022, the Richard M. Bass Outstanding Young Power Electronics Engineer Award from IEEE PELS in 2019, and recognition as an Innovator Under 35 for the Asia Pacific Region by the MIT Technology Review in 2020. She is currently the IEEE PELS Vice President for Global Relations for 2024-2025. Virtual: https://events.vtools.ieee.org/m/415504

Installing Energy Storage Systems (ESS), Photovoltaic (PV) and Electric Vehicle (EV) equipment into power distribution systems can be complicated and expensive. However, Power Control Systems (PCS) introduced into the 2020 National Electrical Code (NEC Article 705) now allow more ESS + PV connected power to new or existing services while minimizing bus sizes, thus making retrofits easier and optimizing new installations. Also, UL3141 (new in 2024) and UL1741 are safety and performance standards which are used to certify PCSs, smart inverters, converters, and the interconnection of EV and Distributed Energy Resources (DERs) in the system. This presentation offers a brief review of NEC 705, and the PCS which meets UL listing requirements. Though applicable to power systems in general, the presentation offers a residential home as an application example of the value of a PCS. The presentation discusses how it affects busbar loading and offers a way to integrate an ESS into existing or new systems. In summary, the PCS, and associated standards make it easier for engineers and installers to maximize the use of multiple energy inputs for efficiency and cost, while ensuring safety and reliability.

Abstract Smart sensors enable a distributed computing approach which significantly reduces the bandwidth requirement for transferring sensor data when the edge computing capabilities in microcontrollers or sensors are utilized. MEMS sensors are now commercially available with a built-in Machine Learning Core (MLC), Finite State Machine (FSM) and Intelligent Sensor Processing Unit (ISPU). These sensors can execute decision trees, neural networks, and symbolic logic directly on the MEMS sensor die. This capability allows the user to develop a variety of applications for consumer, industrial, automotive or medical devices where power consumption for applications needs to be minimized. This presentation will focus on all aspects of on-sensor machine learning that are increasingly being used to build solutions with an always-on user experience with extremely low current consumption, in order of single-digit micro-amps for MEMS sensor applications.

Abstract: USB Type-C™ connector was introduced in 2014. Apple’s iPhone 15 adopted it in 2023. Where USB-C™ connector will be going from here? This talk will cover the basics of USB-C connector and USB Power Delivery (USB PD) specification including the latest update, particularly for using USB-C for battery charging and power applications. We will discuss the potential trend that utilizes the latest Extended Power Range (EPR) features enabling higher power transmission over a USB-C cable up to 240W (DC) Note: USB Type-C™ and USB-C™ are trademarks of USB Implementers Forum, Inc.
