Power Electronics

Toyoda Gosei Co., Ltd. has achieved state-of-the-art high current operation (1) in a vertical GaN power semiconductor developed using gallium nitride (GaN), a main material in blue LEDs. Power semiconductors are widely used in power converters (2) such as power sources and adaptors for electronic devices. However, simultaneous achievement of both high breakdown voltage (3) and low loss (4) (low conduction loss and switching loss) at high levels has been difficult with conventional silicon due to its material properties.

The project raises new hopes to accelerate the advance of electromobility: lithium-based solid state batteries from sol-gel materials are considered a future-proof solution on the path towards safe, low-cost but high-performance batteries able to combine high charging speed with long cycle life. It is mostly conventional lithium-ion batteries that are used in electric vehicles or bicycles. This type of battery enables comparatively high energy and power densities but there is a limit to further voltage increase which puts a stop to ever rising performance levels. Also, the charging speed needs to be controlled to avoid overheating.

Volvo Trucks now introduces its first all-electric truck for commercial use – the Volvo FL Electric for urban distribution and refuse operations, among other applications. Sales and series production of the new model will start in Europe next year. With this introduction Volvo Trucks takes the lead in solutions for electrified goods transport in cities. With better air quality and less noise in the city, it is possible to plan for housing and infrastructure more freely than at present.
