ML algorithms, battery-efficient dashcam kit address parked vehicle monitoring
Aspinity has introduced a suite of new analogML™ algorithms tailored for parked-vehicle monitoring. These algorithms enable continuous vehicle monitoring without compromising battery life, addressing a critical challenge faced by the automotive industry. Additionally, the company has unveiled a dashcam-focused evaluation kit designed to enable precise detection and recording of security events over extended periods without […]
AM radio in cars presents an engineering dilemma
Design engineers are caught between a push to drop AM radios from cars and the radio industry’s pushback. It hasn’t received much attention among all the other news (mostly bad, some good), but there’s some momentum in the U.S. Congress to mandate the inclusion of AM radio receivers in cars. Among all the other issues […]
High-capacity, 100 V automotive MLCCs in miniatures sizes for 48 V architectures
TDK Corporation has expanded its CGA series of multilayer ceramic capacitors (MLCCs) to 2.2μF in 2012 size (2.0 x 1.25 x 1.25mm – L x W x T) and 4.7μF in 3216 size (3.2 x 1.6 x 1.6 mm – L x W x T), with the industry’s highest capacitance*, as 100V products for automotive […]
100 V Trench Schottky diodes boost efficiency in high-frequency power converters
STMicroelectronics has introduced 100V trench Schottky rectifier diodes that boost efficiency in power converters operated at high switching frequencies. Raising power-converter operating frequency, encouraged by the minimal switching losses of technologies like wide-bandgap semiconductors, allows designers to set new benchmarks in power density. However, at elevated frequencies, the energy losses in conventional planar diodes, including […]
What is the best copper alloy for connectors in renewable energy and EV applications?
Copper is important in supporting renewable energy and electric vehicles (EVs). For example, there’s about 5.5 tons of copper used per megawatt (MW) of photovoltaic generation and there’s 183 pounds of copper in an EV, compared with only 48 pounds in an internal combustion engine (IEC) vehicle. Not all copper is the same; there’s a […]
Qi 2.0 reference design offers efficient control and automotive integration
Microchip Technology has released a Qi 2.0 dual-pad wireless power transmitter reference design. Powered by a single dsPIC33 Digital Signal Controller (DSC), the Qi2 reference design offers efficient control for optimized performance. A key feature of the new Qi2 standard, recently released by the Wireless Power Consortium (WPC), is the introduction of a Magnetic Power Profile (MPP) […]
Solving thermal challenges in EV charging
In the ever-evolving landscape of electric vehicle (EV) technology, the pursuit of faster charging speeds and increased efficiency stands as a paramount goal. As significant improvements in EV technology continue in tandem with growing government support, the demand for electric vehicles has never been higher. However, amidst this drive for progress, one critical aspect that […]
How can carbon nanotubes improve interconnect performance?
Carbon nanotubes (CNTs) have been proposed for reducing fretting wear in connectors used in high-vibration environments like vehicles. They can also be used to make contacts with lower contact resistance and higher corrosion resistance compared with silver (Ag) plating, and they have been used to reduce the weight in some shielded cables by 25% or […]
Supercapacitors handle 9 WVDC, save board space
Knowles Precision Devices announced its latest Electric Double Layer Capacitor (EDLC), or supercapacitor, modules are now available. Based on Knowles’ Cornell Dubilier brand DGH and DSF Series supercapacitors, these cutting-edge capacitors use a three-cell package for higher operating voltages and printed circuit board space savings. Knowles Corporation acquired Cornell Dubilier in 2023 to expand its offering […]
