Wireless devices have a pivotal role in our everyday life: just think of smartphones and computers and how frequently we rely on continuous power supply or long battery life. RF energy harvesting systems allow limiting battery use and improve safety by offering advantages to the entire application market that is expected to grow by 22% … Read more
When selecting cells for a power battery, it is useful to have the ability to quickly compare various cell technologies, and calculate the resulting pack resistance and efficiency, independently of capacity and voltage. This article proposes a way of doing so, using the “short discharge time”, the theoretical time required to discharge a full cell … Read more
As a power supply output current requirements continue to increase, it is important for the design engineer to pay close attention to inductor power losses and their affect on overall power supply efficiency. This paper introduces the basic formulas to determine the approximate inductor power losses. AbstractAs a power supply coutput current requirements continue to … Read more

Each new generation of powertrain controls challenges systems designers with higher complexity and the need for increased computing performance. Driven by global regulations, performance requirements include increased throughput, memory, peripheral and advanced packaging capabilities. Increasingly tougher emission regulations, as well as unprecedented fuel efficiency targets, require sophisticated systems that extend well beyond traditional spark ignition … Read more
Among internal combustion engines, diesel engines boast excellent thermal efficiency and can burn fuel that is not highly refined. They use a compression ignition system in which intake air is pressurized and fuel is injected into it, causing it to self-ignite. Such systems are not prone to knocking even when supercharging is used, so most … Read more
