Reliable SiC Power Devices for Automotive Applications COVER STORY
The mission of Rohm is to produce power devices that meet high reliability standards at all times. This philosophy has enabled Rohm to increase the SiC business in the automotive field with a steadily growing demand and close cooperation with customers. This article focuses on automotive-grade SiC power devices, including some of their common applications and reliability data. In detail, this comprises an overview of SiC MOSFETs and Schottky barrier diodes and their main target applications, e.g. battery charging systems and power train inverters. Special focus is put on the qualification process of our devices including experimental results from reliability tests, such as gate oxide reliability, cosmic radiation ruggedness and SiC MOSFET’s body diode bipolar degradation effect.
The prospects for electric vehicles (EV) have greatly improved, turning electric mobility into a subject of significant interest. Car manufacturers, industrial companies and research institutes have joined forces in order to push forward the planned mass production of hybrid and electric vehicles. In doing so, newly developed power electronic systems are also being integrated into EVs. Due to the special requirements demanded by automotive OEMs, system developers are confronted with new challenges. The required space, weight and efficiency play an important role. Furthermore, the overall system cost and the expenses should remain low, while at the same time top-quality and reliability need to be guaranteed for the products.
