Defence applications with 270 VDC input must meet stringent EMI, environmental and power-related standards such as MIL-STD-461, MIL-STD-810 and MIL-STD-704. The design process is further complicated by SWaP-C requirements.
Viable power-switching devices based on gallium nitride (GaN) technology have turned the corner — and there’s no going back. They offer greater efficiency and power-handling performance compared to their well-established, widely available silicon MOSFET counterparts.
This case study examines a suite that produces cost-effective imagery at a scale and resolution previously unseen. Innovative computer-vision and photogrammetry techniques help to create cutting-edge 3D models, aerial photographs and elevation data.
The number and variety of automobile electronics and accessories is growing, fuelling the need for more advanced power components to support these electronics. These systems rely on multiple battery chemistries and can operate at different voltages.
With the ability to illuminate large areas, either indoors or outdoors, lighting engineers and designers are increasingly directing their attention towards the quality and controllability of the illumination.
The demand for high-fidelity audio continues to drive sound engineers for 32-bit audio solutions with higher frequency response, higher resolutions and greater signal purity. Much can be learnt from these next-gen designs.
Learn about the causes that can be attributed to an asymmetrical current distribution. Discover the influence of the driver concept used (individual or central driver) as well as the impedances contained in a system.
Understand the fundamentals of switching and multiplexing to build a smarter test system that can address your needs today and in the future.
This novel solution enables high voltage low current to be distributed throughout a system, minimising distribution losses, while providing low voltage high current direct from the 48 V input in the most efficient manner possible.
The design of the PCB, the housing and the anticipated end-use environment all play a major factor in the decision whether to use a coating or a resin.
Power Factor Corrected AC rectification has been addressed in a variety of ways over the past three decades. The wide variation of worldwide AC line voltages, however, has imposed significant design trade-offs.
Traditional TCO metrics for embedded systems are now worthless. For an accurate idea of lifetime costs it is now essential to factor in the fast-changing IoT landscape.
New compact solutions for device packaging, silicon integration and MOSFET technology work well with over a narrow voltage range. Efficiency and throughput power tends to drop off dramatically, however, over a moderate to high input range.
Smart cars continue to expand autonomous driving tasks that assist or even outright outperform humans. However, the question remains: Are system architects ensuring that there is an appropriate allocation of responsibility, visibility, and capability for emergency handling between driver and electronic control systems?
