A closer look at wire bonding

Wire bonding technology – widely utilized in the microelectronics and power electronics industries since the 1970s – is finding its way into interesting new applications in the growing EV industry – in particular, battery connections. We’re quite certain that a few EVs are using wire-bonding technology for production battery pack connections, but Charged was unable… Read more »

Toshiba launches new opto-isolated IGBT gate pre-driver IC for inverters

Toshiba’s new TB9150FNG, an opto-isolated Insulated Gate Bipolar Transistor (IGBT) gate pre-driver IC, features various enhanced protective functions for the inverters of electric and hybrid vehicles. As the control and drive functions of an inverter have different operating voltages, they must be isolated from each other. This is typically accomplished with a device such as… Read more »

Infineon and TDK partner to help developers design inverters quickly

Infineon Technologies has joined forces with TDK to develop an integrated solution for inverters to be used in e-mobility powertrains. The idea is to enable developers to test and implement drive concepts quickly and easily. To create an inverter that’s optimized for automotive applications, Infineon and TDK redeveloped the key components and matched them perfectly… Read more »

Winning Google Little Box Challenge inverter powered by GaN Systems transistors

Google and the IEEE Power Electronics Society established the Little Box Challenge to stimulate the development of inverters, key components of both solar energy installations and EV systems. The challenge to engineers: “Figure out how to shrink an inverter down to something smaller than a laptop (a reduction of 10× in volume), and you’ll win… Read more »

Faraday Future awarded patent for FF Echelon Inverter

EV startup Faraday Future (FF) has applied for more than 100 patents over the last year. This week it announced that its first one has been granted, for a new assembly process called “FF Echelon Inverter.” The inverter is designed to be small and simple. FF claims it achieves 20-30% greater power density than competitors’… Read more »

DOE issues $25-million funding opportunity for next generation of electric machines

Gallium nitride power diode shows near-ideal performance in all aspects simultaneously

Silicon-based semiconductors are approaching their performance limits, so researchers are investigating materials such as gallium nitride (GaN) as potential replacements. A team of engineers from Cornell, Notre Dame and the semiconductor company IQE has created GaN power diodes capable of serving as the building blocks for future GaN power switches. Alas, GaN is prone to… Read more »

The DOE’s SBIR/STTR programs offer EV-related R&D funding for small businesses

The DOE has announced a new batch of topics for the 2016 Small Business Innovation Research and Small Business Technology Transfer (SBIR/STTR) programs. Under the SBIR and STTR programs, federal agencies set aside portions of their R&D budgets for small businesses. Companies that win awards keep the rights to any technology developed, and are encouraged… Read more »
