Electric vehicles and expectations for wide bandgap power devices

Electric vehicles (EVs) will be one of the core next-generation automotive technologies. This paper presents an overview of EV development. For the on-board power electronics of EVs, it is necessary to reduce their size, lower their cost and increase their efficiency. Wide bandgap (WBG) power devices are expected to be used to attain these aims. Packaging technologies need to be considered for using WBG power devices. Electromagnetic interference (EMI) must be detected for high switching dV/dt and dI/dt applications.
