Advanced Materials for Magnetic Silence

High-performing advanced magnetic materials are now available that help to handle challenges in hybrid/electrical vehicles. These are challenges related to conducted and radiated electromagnetic interference. Automotive engineers are encountering newer challenges with fully electric vehicles or EVs and hybrid electric vehicles or HEVs become more popular. The above challenges are so intriguing, engineers now have a fundamental discipline for it, noise vibration and harshness or NVH engineering. Read more [...]

New Battery Technology for UPS

Most people know of the Lithium-ion battery technology in use mainly due to their overwhelming presence in mobile sets. Those who use uninterruptible power supplies for backing up their systems are familiar with the lead-acid cells and the newer lithium-ion cells. Another alternative technology is also coming up mainly for mission-critical facilities such as for data centers. This is the Nickel-Zinc technology, and it has better trade-offs to offer. But the Nickel-Zinc battery technology is not Read more [...]

Power Transmission Through Lasers

Wireless power transfer has considerable advantages. The absence of transmission towers, overhead cables, and underground cables is the foremost among them, not to exclude the expenses saved in their installation, upkeep, and maintenance. However, one of the major hurdles to wireless power transmission is the range it can cover. But now, Ericsson and PowerLight Technologies have provided a new proof of concept project that uses a laser beam to transmit power optically to a portable 5G base station. Wireless Read more [...]

TI Driver for BLDC Motors

When simple motors were more frequently used, it was relatively easy to design products with them. Controlling such motors was simple, whether it was a brushed DC motor or a single-phase AC motor. There was no need for sophisticated hardware or software for designing a product with a motor. However, sophisticated BLDC or brush-less DC motors are replacing most of the above motors because of several advantages like quiet operation and high efficiency. But these advantages come at the cost of design Read more [...]

Where Do You Use Encoders?

All kinds of mechanical systems use a critical component commonly known as an encoder. Large industrial machines performing delicate work, high-precision prototyping, or repeatable tasks use encoders predominantly. Production of advanced electronics also requires the use of encoders. Encoders can be linear, angle, or rotary and the electronics sector uses them in some form or the other. Semiconductor fabrication, with its small components and work areas, requires encoders of the highest resolution Read more [...]

Battery Electrolyte from Wood

Although there exist several types of batteries, all of them function with a common concept—batteries are devices that store electrical energy as chemical energy and convert this chemical energy into electricity when necessary. Although it is not possible to capture and store electricity, it is possible to store electrical energy in the form of chemicals within a battery. All batteries have three main components—two electrodes or terminals made of different metals, known as anode and cathode, Read more [...]

Improving Computer Vision with Two AI Processors

Computer vision is becoming a necessity in IoT and automotive applications. Engineers are trying for the next level in computer vision with two AI processors. They hope that two AI processors will help to make computer vision not only more efficient but also more functional. One of the fastest-growing applications of artificial intelligence, computer vision is jostling for attention between prestigious fields like robotics and autonomous vehicles. In comparison to other artificial intelligence Read more [...]

Low-Power Circuit Timing using SPXOs

A wide range of electronic devices relies on circuit timing as a critical function. These include microcontrollers, Bluetooth, Ethernet, Wi-Fi, USB, and other interfaces. In addition, circuit timing is essential for consumer electronics, wearables, the Internet of Things (IoT), industrial control and automation, test and measuring equipment, medical devices, computing devices and peripherals, and more. Although designing crystal-controlled oscillators seems an easy process for providing system timing, Read more [...]

Cooling Modes in Electronic Loads

Applications based on renewable energy are thriving. This is leading to a requirement for increased testing of devices that generate renewable DC power—devices like solar panels, fuel cells, and batteries, to name a few. This testing is typically by employing electronic loads, mostly programmable and with a design that can draw various specified amounts of power from the source. In the lab or on the production floor an electronic load is the most suitable instrument to characterize devices producing Read more [...]

A Bending and Stretching Battery

All electrical and electronic equipment we use in our daily lives requires power to operate. Movable equipment depends on batteries for their mobility. We are used to various types of batteries, like dry cells, lead-acid batteries, rechargeable Ni-Cd and Li-Ion batteries, and so on. However, all the batteries in common use are rigid, non-flexing structures. That may be changing now, as some researchers have claimed to have created a battery that is flexible and stretchable like a snake but unlike Read more [...]
