Capacitors are found throughout switch mode power converters. The first FAQ in this series of three articles looked at the X and Y safety capacitors used in the input filtering section. The second article looked inside the power converter and considered dc link capacitors as well as energy storage and pulse power capacitors. This final […]
DC link, energy storage, and pulse power capacitors
The first article in this three-part FAQ series reviewed safety capacitors (sometimes called high-frequency bypass capacitors), primarily for filtering electromagnetic interference (EMI) on the input of mains-connected power converters such as power supplies, battery chargers, and motor drives. This FAQ moves deeper inside the various types of power converters and will consider DC link capacitors, […]
Safety capacitors for EMI filtering and voltage isolation
This is the first article in a three-part FAQ series on capacitors used in power-handling applications. This article will consider safety capacitors for filtering electromagnetic interference (EMI, also called radio frequency interference, RFI) on ac power lines, for antenna coupling, and for providing voltage isolation in DC/DC converters. Part two will look into “DC link, […]
How “green” is your Artificial Intelligence?
Artificial intelligence (AI) systems face a set of conflicting goals: being accurate (consuming large amounts of computational power and electrical power) and being accessible (being lower in cost, less computationally intensive, and less power-hungry). Unfortunately, many of today’s AI implementations are environmentally unsustainable. Improvements in AI energy efficiency will be driven by several factors, including […]
Benchmarking AI from the edge to the cloud
Artificial Intelligence (AI), machine learning (ML), and deep learning (DL) are fast-changing and complex fields. Until relatively recently, there were no performance benchmarks for AI, ML, or DL systems. That is changing. Today, several industry organizations have developed AI, and ML benchmarks, with more complex benchmarks for DL coming soon. Those efforts stretch from the […]
Artificial Intelligence, Machine Learning, Deep Learning, and Cognitive Computing
Artificial intelligence (AI) is the field in computer science where machines attempt to mimic human reasoning to recognize and analyze situations and make decisions. AI has been under development for decades, but only recently has computing power and memory become high enough in performance and low enough in cost to make AI a practical tool […]
Flow battery application challenges and considerations – Virtual Roundtable (part 2 of 2)
In this second part of EEWorld’s “virtual roundtable” discussion on flow batteries, our panelists delve into the impact that the emergence of flow batteries is having on energy storage compared with conventional rechargeable batteries: What factors determine when flow batteries are more cost-effective than rechargeable batteries? How do the maintenance and monitoring needs of flow […]
Flow battery capabilities and performance – Virtual Roundtable (part 1 of 2)
In this first part of EEWorld’s “virtual roundtable” discussion on flow batteries, our panelists delve into the impact that the emergence of flow batteries is having on energy storage compared with conventional rechargeable batteries: What performance advantage do flow batteries have? What is the barrier to large scale deployment? And how do the environmental or […]
Formula E Gen3 smaller batteries, regen and fast charging
The battery and energy systems of Formula E cars will change significantly with the introduction of the third generation (Gen3) design in 2022. The Gen3 specifications are scheduled to last three seasons until 2025. In Gen3 cars, the battery will be lighter (so will the entire car), it will be capable of handling fast charging […]
Formula E teams and technology partners
Formula E has a total of 12 teams with 24 drivers and 24 cars. In addition, there are numerous technology sponsors. This third and final FAQ in EEWorld’s Formula E series reviews some of the current technology partnerships of the various teams. Powertrain partners are particularly important, and battery cooling is becoming an issue, especially […]
