(LP1) Energy Harvesting and Digital Isolation for IoT Sustainability, Safety, and Data Integrity
By Karthi Gopalan (Analog Devices)
We live in a connected world with tens of billions of IoT devices, soon trillions that reside in wired & wireless domains. We have a tremendous opportunity to transform how we live and work and strive to improve productivity to make the world better and safer! The presentation will demonstrate how intelligent energy harvesting and innovative digital isolation solutions can have a big impact: For wireless IoT, energy harvesting has the potential to up the power sustainably. A new chip-scale energy harvester will exemplify an accurate way to harvest thermal energy widely available in industrial environments. Safety and data integrity are significant concerns for wired IoT in noisy and dangerous high voltage environments, typical for many of these applications. Next generation integrated digital isolation provides accurate current and voltage sensing for robots, energy metering, battery management, and protected Gbps communication with industrial or medical instruments. Compact isolated DC/DC converters provide easy-to-use, EMC compliant, fully integrated multi-protocol transceivers for Industry 4.0. Technologies are there to achieve better IoT sustainability, safety, and data integrity – we need to leverage them at a grander scale.
(LP2)?The Rise of Wireless Power Networks
By Cesar Johnston (Energous)
Projected to reach 39.3 billion devices by 2025 (according to IDC’s “Worldwide Global DataSphere IoT Device and Data Forecast”), the IoT ecosystem is expanding at a rapid rate. These billions of internet-connected devices all share one common need: reliable and consistent power. However, most IoT devices in current deployments rely on either cumbersome charging cables or on batteries that must be frequently replaced at varying intervals, placing massive strains on maintenance teams and limiting the value these devices can deliver. In this talk we will discuss the rise of Wireless Power Networks that not only deliver reliable & consistent wireless power, but also helps aggregate IoT device data transfer to the Cloud from the next generation of IoT deployments.
(LP3)?The Supercapacitor – A Versatile Energy Storage Device and How to Use it
By Dr. René Kalbitz (Würth Elektronik)
Supercapacitors are easy to use short-term energy storage devices, which are in many, but not all, aspects comparable to batteries. They require, like any other energy storage system, a certain infrastructure in order to store and deliver their energy. In the course of this keynote, we will discuss important properties of Supercapacitors and key features of the design-in process.
(LP4)?Wireless Charging for Low-Power Applications
By Gopi Akkinepally (Renesas Electronics)
Low-power devices are typically in small form factors which don’t have space to add a big charging port, often needing waterproofing and higher reliability. Wireless power is a natural fit to address these issues. However, the non-standard industrial design of many of these devices has made it challenging to add wireless charging. In this talk, Gopi will cover various options available for low-power devices, as well as the systematic design methodology system designers can use to integrate wireless charging into their systems.
(LP5)?Minimizing the Energy Footprint of the Digital Economy with High Bandwidth IVRs
By Trey Roessig (Empower Semiconductor)
The exponential increase in the amount of data being communicated and processed around the globe is driving the energy consumption of data centers and communications networks to 17% of total electricity demand worldwide by 2030?1, dramatically increasing pollution, carbon emissions and cost. Empower Semiconductor was founded with the mission to “minimize the energy footprint of the digital economy” by developing novel fully integrated power management solutions that both increase the performance and reduce the power consumption of energy-hungry, data-intensive applications. Empower Semiconductor solutions integrate dozens of components into a single IC increasing efficiency, shrinking footprints by 10x and delivering power with unprecedented simplicity, speed & accuracy and with zero discrete components for a wide range of applications including mobile, wearables, 5G, AI, and data centers.

(EN1) Why Sustainable Energy is Essential for a Better Future
By Hassane El-Khoury (onsemi)
Energy is essential to economic growth and prosperity. While renewable energy will mitigate climate change, it needs to be cost competitive with traditional forms of energy and easily accessible to ensure a sustainable future that meets the energy needs of future generations. A 21st century zero-emission energy network must be enabled by power electronics that minimize adverse impacts of green-house emissions and transition global economies to a sustainable growth path. Innovations in power semiconductors are at the heart of this transformation, both in switching and packaging technologies, as well as innovations in new materials such as Silicon Carbide (SiC), offering extended driving range and high power and performance for EVs. Hear onsemi CEO Hassane El-Khoury share his insights into energy infrastructure and how onsemi is not only working on its own net-zero goals but innovating to deliver high-performance products today for the sustainable ecosystem’s energy needs of tomorrow.
(EN2) From Sun to Wheels - Silicon Carbide is the Future of Green Energy
By Guy Moxey (Wolfspeed)
As the world accelerates its adoption of wide scale green energy, Wolfspeed is leading the industry-wide transition from silicon to Silicon Carbide. Power derived from the sun or wind must be converted, connected and distributed through power electronics systems that operate with the highest efficiency, smallest size and lowest system cost. Silicon Carbide increases both power system efficiency and power density at every stage of this ecosystem. Energy storage for overall smart grid use and stability requires distributed energy resources that localize clean energy generation, allow point-of-load energy storage and utilize bi-directional power. Silicon Carbide, as a proven scalable technology, dramatically improves the power architectures used in such systems so that the power semiconductor is no longer the weak link, or gating factor, for global green energy.
(EN3)?Broad adoption of SiC MOSFETs in EVs accelerates electrification and brings benefit to industrial applications
By Filippo Di Giovanni (STMicroelectronics)
领英推荐
Since their introduction some years ago, SiC products have sparked car electrification by improving efficiency, reducing heat waste, and taking less space. These factors are enticing buyers by delivering longer driving ranges – and reducing range anxiety, making cooling systems less complex and cheaper, and allowing faster charging. Making SiC products in automotive-grade versions since introducing them to the market has been a big challenge. Dedicated products such as ST’s 2nd -generation MOSFETs were the first to fully address automotive requirements. These are now complemented by STPOWER GEN3 with further significant improvements in both on-state and switching performance. STPOWER GEN3 products are fully tested and debugged in the harsh car-hood environment and can be safely deployed across the full spectrum of industrial applications, including charging stations, which represent a large chunk of the highly diverse industrial market.?

(EN7)?Modern gate drivers for SiC MOSFETs short-circuit protection
By Gabriel Cretu (Infineon Technologies)
Today’s advancements in SiC MOSFETs development enable even higher performance in their operation. But this performance improvement results in decreased short-circuit robustness. In the end this means that the short-circuit protection needs to be faster and more precise. In this presentation we will show that today’s gate drivers with DESAT are still a great solution for SiC MOSFETs short-circuit protection. We will highlight the requirements and performances of the DESAT protection circuit in modern gate drivers from Infineon.
