Field-oriented control, also known as vector control, is a calculation-intensive algorithm for motor control which is now practical due to advances in ICs; it offers improved efficiency along with superior control of torque and other performance parameters. Motor control—and doing so accurately and efficiently—is a topic of great interest. Field-oriented control (FOC), sometimes called vector […]

Don’t get burned about LED UV
Another myth busted: You needn’t worry about ultraviolet light coming from ordinary LED bulbs. We recently checked a batch of LED bulbs for the amount of blue light they gave off. This effort came in response to claims from some in the alternative medicine crowd that LED bulbs gave off inordinate amounts of unhealthy blue […]
Heat sinks, Part 2: Available components
Part 1 of this FAQ looked at the basic issues associated with cooling and heat sinks. Part 2 focuses on the various heat sinks available. Q: Are heat sinks limited to a single component such as an IC? A: No, there are heat sinks which fit entire unit or chassis cool such as those which […]
Taking resistor technology beyond RoHS
By Stephen Oxley, Senior Engineer Applications and Marketing, TT Electronics Lead has long been recognized as a serious environmental hazard. It has a detrimental effect on the workings of the human central nervous system, and this is particularly acute when children are exposed to it. Based on the findings of scientific research conducted during the […]
Sights at the IDT tech seminar
Integrated Device Technology hosted a one-day technical seminar in Detroit covering wireless power, sensing, and timing technologies. Here are some of the notable demos we saw running there. NEXT PAGE: A better way to track motor shaft position: Inductive sensing
Choosing a capacitor? Ripple current capability matters as much as Farads
by Derick Stephens, KEMET Corporation Selecting capacitors for decoupling and filtering in power circuits may seem like a basic chore for electronics designers. Getting it right, however, can critically influence reliability and longevity, but is complicated by the fact that parameters tend to change with factors such as the temperature and operating frequency. Proper attention should […]
Heat sinks, Part 1: Thermal principles
A heat sink is a non-electronic, passive mechanical component that has a vital role in the reliability and performance of ICs, PC boards, modules, chassis, and more. Heat sinks often don’t get much attention, at least not in the early stages of a design. This FAQ will look at the basic thermal principles of these […]
