GM is developing a next-generation power inverter capable of 55 kW peak/30 kW continuous power. According to GM’s Sean Gleason, who gave a presentation on the project at the DOE’s Annual Merit Review, GM is almost two-thirds of the way through the $16.6-million project ($6 million of the funding support came from the DOE), which… Read more »

The European MotorBrain project has presented a prototype of a lightweight electric motor system that integrates the motor, gear drive and inverter, and requires no rare earth metals. The prototype motor system is three quarters the size of models from the beginning of the project in 2011, and, at less than 77 kg (170 lbs),… Read more »
Topping the list of EV inhibitors are cost and consumer perception of long-term reliability of the vehicle. After batteries, power electronics contribute the greatest cost to EVs, when compared to a traditional internal combustion engine (ICE) vehicle. Additionally, inverters and converters are among the most stressed powertrain components. Increasing inverter performance, reliability, and lifetime –… Read more »
