Fuji Electric and Robert Bosch collaborate on SiC power semiconductor modules for EVs
Japan-based power electronics manufacturer Fuji Electric Co Ltd and automotive parts maker Robert Bosch GmbH of Reutlingen, Germany have agreed to collaborate on silicon carbide (SiC) power semiconductor modules for electric vehicles (EVs) that feature package compatibility.
With power semiconductors are essential components in EV inverter systems to convert and control electric power, SiC power semiconductors (which have characteristics such as high breakdown voltage and low loss) are becoming increasingly prevalent. They enable automotive manufacturers to achieve smaller and lighter inverter systems, extending the cruising range (one of the critical challenges for the widespread adoption of EVs).

Fuji Electric says that its SiC power semiconductor modules for EVs incorporate its unique packaging technology, contributing to the realization of compact and highly efficient inverter systems with high power density. Furthermore, by flexibly modifying the size and number of mounted chips, these modules can accommodate a wide range of power requirements and circuit configurations from automotive manufacturer customers.
Moving forward, both companies intend to develop SiC power semiconductor modules with mechanical compatibility in terms of package outer dimensions and terminal positions. This will enable either module to be integrated into an inverter system without additional mechanical modifications, minimizing the adjustment effort required for customers when using both module options in their systems. This collaboration aims to shorten design periods and contribute to diversifying procurement sources. As a result, customers will be able to use SiC power semiconductor modules from both companies without altering their inverter system specifications, leading to reduced design time and diversified procurement.
Furthermore, both companies plan to jointly develop user application technologies related to cooler design and various terminal connections when integrating SiC power semiconductor modules into inverter systems, and plan to provide technical support to customers. Through this initiative, Fuji Electric and Bosch aim to contribute to enhancing supply chain stability and further promoting the adoption of electric vehicles.
