The quad family of Supercapacitor Auto Balancing (SAB) MOSFETS offers a simple, economical and effective method to balance and regulate supercapacitors rated at a higher voltage. The chip is built using ALD EPAD proven production technology. The ALD810030 stabilizes supercapacitors that can be used in a wide variety of applications such as actuators, telematics, solar […]
Renewable energy
Cars powered solely by solar energy? Sure…but with a very big “but”
Lately, I’m seeing a lot of cases where solar power is posited as the energy solution for “everything.” And why not? It’s free and ubiquitous, and it feels good to say you are using it. I recently read a column by someone (sorry, I couldn’t find it afterward) about the easy practicality of cars powered […]
Proof-of-concept platform evaluates ambient light and heat micro-power sources
Trameto has introduced a proof-of-concept platform for evaluating how to generate a reliable micro-power source from ambient light and heat. Called Severn, the compact platform can be used as a prototype because its size and form factor could be adopted for production. An engineering sample of the TM2040, a four-input, smart EH PMIC is at […]
Integrated ac-dc power stages handle up to 950 V
Optimized performance, efficiency, and reliability in high-voltage power supplies need to be combined with reduced bill-of-material (BOM) count and cost, as well as lower design efforts. With its 5 th generation fixed-frequency (FF) CoolSET portfolio, Infineon Technologies AG offers the right components to meet these needs and effectively manage the critical design trade-offs. The new 800 V and 950 V […]
GaN half-bridge power ICs enable megahertz-range switching frequencies
Navitas Semiconductor announced the industry’s first GaNSense half-bridge power ICs. These half-bridge ICs enable a new level of MHz switching frequencies while dramatically reducing the system cost and complexity compared to existing discrete solutions. GaNSense half-bridge power ICs integrate two GaN FETs with drive, control, sensing, autonomous protection, and level-shift isolation, to create a fundamental […]
Signal transformers for BMSs sport high isolation, working voltages
With WE-BMS, Würth Elektronik presents signal transformers for battery management systems which, thanks to their galvanic isolation of 4300 VDC/1 min and high operating voltage of up to 1000 VDC, are ideal for use in energy storage systems, E-bikes, or E-scooters. Besides the transformers, the new WE-BMS series components also include at least one common-mode choke […]
3D printing and bacteria blend for solar harvesting
Leveraging apparently unrelated technologies links bacteria and photosynthesis to additive manufacturing for energy harvesting. Additive manufacturing—perhaps better known as 3D printing—has radically changed the production reality for everything ranging from unique, one-of-a-kind structures to spare-parts inventory to lower-volume, tooling-free productions. It’s also enabled the creation of structures that would be difficult if not impossible to […]
Demo platform enables study of micro-energy harvesting apps
Trameto announces a demonstration platform that enables engineers to quickly evaluate how micro-energy harvesting can reduce or eliminate the use of batteries in IoT devices such as sensors and the wireless modules to which they may be connected. It is based on Trameto’s OptiJoule technology and uses an engineering sample of the TM2040, a four-input, smart […]
Current-sense shunt resistor offers 0.5 milliohm resistance, 3-W power rating
High-efficiency current sensing requires low resistance values. However, lead resistance may cause inaccuracies in sensing measurement for ultra-low resistance values. Four terminal Kelvin connections with separate sense and current flow connections eliminate the detrimental effects of lead resistance yielding a very accurate measurement of the power delivered. Stackpole’s CSSK3637 is a four-terminal device offering resistance […]
Battery test system boosts safety, performance of electric vehicles
A new Battery Test System (BTS) for electric vehicle (EV) testing is designed to help tier-one suppliers and automakers adapt to the complexity and scale of EV battery testing through enhanced customization, automation, and connection of data across the entire battery test workflow to ensure performance and accelerate time to market. Batteries are at the…
