There are over 20 categories and subcategories of fuel cell technologies. This article will review several of the most common fuel cell technologies, especially as related to commercialization. This is the first of a three-part FAQ series. Part two will look into “Fuel Cells for Backup Power, Microgrids and Renewable Energy” and part three will […]
AI applications and emerging computing architectures – Virtual Conversation (part 1 of 2)
Hosted by Jeff Shepard, EE World has organized this “virtual conversation” with Gary Bronner (GB), Senior Vice President with Rambus Labs. Mr. Bronner has generously agreed to share his experience and insights into AI applications and emerging computing architectures. JS: What is usually the biggest challenge designers face when first using artificial intelligence? GB: One […]
Embedded systems software and programming for a safer world
Functional safety is an important feature in many embedded systems today. Designers need to know the specific safety integrity levels that must be met in various application environments and software development standards and guidelines. The use of an integrated development environment can efficiently bring these various requirements together to maximize the productivity of the development […]
Securing embedded systems in a hostile world
The design of security for embedded systems is a critical and difficult task. Security requirements are often not fully identified at the beginning of the project. Once they have been identified they are not necessarily static and can change multiple times through the design cycle. One reason for changing security requirements is that the various […]
Managing power consumption and dissipation in embedded systems for a greener world
Three of the keys to successfully managing power consumption and dissipation in embedded systems are using various active power management techniques, power-aware code and software optimization, and making power management an integral part of the design flow process from the beginning. Active power management can include the use of power gating, clock gating, dynamic voltage […]

Capacitors for power converter output filtering
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, […]
