This paper reviews the state of the art of electric drives technology in three specific areas (a) technical requirements of high−performance ac machines control, (b) most popular electrical machines and (c) control techniques. Key development trends including the dominance of ac adjustable speed drives in new applications,...
While every business strives to ensure uptime and availability for customers, operators within the utilities space have additional regulatory and monitoring requirements that must be adhered to as well. For both financial and safety reasons, utility companies are building high-availability smart sites to help minimize...
There are generally two different methods used to protect the pressure transmitter and/or the pressure switch from high temperatures. These two proven methods are done through the use of cooling elements and standoff piping. Provided below are guidelines on how to protect the pressure devices from extreme temperatures...
Ironless rotor DC motors present characteristics highly desirable for speed and position servos. Due to the absence of iron there is no cogging, and the rotor has no preferred positions, phenomena which tend to deteriorate precision of a servo. Furthermore, their low rotor inertia improves the dynamics of the entire drive...
This white paper presents a technical overview of TE Connectivity’s (TE) new KOAXXA SMA RF interconnect product portfolio. Our KOAXXA SMA product embodies TE’s strategic vision for the future of RF connector product design and manufacturing.
Innovative product features that are part of the KOAXXA SMA product...
The realities of finite petroleum resources and growing global energy needs along with the confidence that we are indeed experiencing global warming caused by burning fossil fuels have awakened governments and the media to “green” concerns. Both organizations and individuals have started to pay attention to...
Bringing efficiency, cost, and volume together is a major balancing act, and getting the right percentage is essential.
As end applications demand more and more processing power, increased bandwidth, and more storage capacity, datacenters are under fire to manage and support these needs while balancing energy conservation...
In recent years, photovoltaic power generation, electric vehicles, etc. have spread rapidly from the perspective of global environmental protection and are used in various regions around the world. For this reason, there is a growing requirement to expand the operating temperature range of fans to support both low and...
Designers building power inductors for today’s highly volume mobile markets face a difficult dilemma. On the one hand the market demands higher performance systems with additional functionality running at higher current levels. On the other hand it pressures product designers to squeeze that additional functionality...
Trade-off between best attenuation effectiveness and minimum leakage current.
Network filters (EMC filters) are often regarded as a Blackbox and, justifiably, the user doesnt concern himself with its inner workings. However, for the effective use of filters, it is advantageous to have some background knowledge. The...
This white paper presents a reference design of an IoT sensor system optimized for wearable applications. It describes the challenges that may arise during the feasibility study and design phases of a wearable device and gives practical advice for hardware designers.

Current fiber optic technology fails to deliver a High Performance Interconnect solution which provides service and manufacturability, high density channel count, low loss optical performance and high reliability.
New broadband service networks, high fiber densities, increasing end - user bandwidth demands and...
The design of AC/DC power supplies is inevitably evolutionary, rather than revolutionary. It develops largely as a result of gradual improvements in semiconductors and passive component technologies and materials. Invariably, power supply design objectives involve not only meeting basic input and output specifications...
The explosive growth in Internet-connected devices, or the Internet of Things (IoT), is driven by the convergence of people, device and data across the web. Future growth will be strongly influenced by wearable technology as products transition from the laptop to the pocket to the body.
Activity trackers are leading...
