Battery Management Getting Competitive For EVs
By Ed Sperling - 07 Apr, 2022 - Comments: 0

The success or failure of future electric vehicles will depend on where and how those cars are used, as well as significant advances in battery materials, energy density, and some very complex battery management systems. Battery power needs to be balanced, stored for extended times, and delivered to wherever it is needed most in real time. This is a huge challenge, and nearly everything in a... » read more

Research Bits: March 15
By Jesse Allen - 15 Mar, 2022 - Comments: 0

Interferometer on chip Researchers at the University of Rochester developed an optical interferometer on a 2mm by 2mm integrated photonic chip that is capable of amplifying interferometric signals without a corresponding increase in extraneous noise. Interferometers merge two or more sources of light to create interference patterns that provide information able what they illuminate. “If y... » read more

Safe And Reliable MOSFET Operation In Bidirectional Power Switch (BDPS) Applications
By Infineon - 05 Jan, 2022 - Comments: 0

The global market for battery-powered applications is rapidly growing, including power tools, service robots, light electric vehicles, and many others. The evolution of switched-mode power supply (SMPS) topologies enables designers to ensure safe charging and discharging of the equipment’s battery using bidirectional converters through the same terminal. However, to meet the safety requiremen... » read more

Traction Inverters Are A Key Application For Electrified Vehicle Designs
By Infineon - 01 Dec, 2021 - Comments: 0

High efficiency increases range and reduces cooling efforts while optimized power density assists with space and weight. As sales volumes increase, the focus is shifting to automated manufacturing with increasing quality requirements. The most fundamental system in all electric vehicles is the powertrain and, at the heart of this is the traction inverter that converts energy stored in the ba... » read more

Don’t Toss That Gasoline Engine Just Yet
By Ed Sperling - 07 Oct, 2021 - Comments: 0

As auto makers race toward increasingly electrified vehicles, there is an entire after-market effort underway that was started decades ago, largely by hobbyists. And after decades of playing around with batteries and novel technologies, they've come to roughly the same conclusions as the owners of newer electric vehicles. There are definite advantages as well as some limitations, and the needle... » read more
