Fuji Electric Co., Ltd. announced an agreement with Robert Bosch GmbH (Bosch) to collaborate on silicon carbide (SiC) power semiconductor modules for electric vehicles featuring package compatibility. The partnership targets faster design cycles for automakers and greater flexibility in sourcing as EV adoption accelerates.
SiC devices are increasingly used in EV inverter systems for their high breakdown voltage and low loss, enabling smaller, lighter, and more efficient powertrains that extend driving range. Fuji Electric’s SiC modules leverage proprietary packaging to deliver high power density and efficiency, with flexible chip sizing and counts to meet a wide spectrum of power requirements and circuit configurations.
Under the collaboration, the companies plan to develop SiC modules with mechanical compatibility—aligned package outer dimensions and terminal positions—so either module can be integrated into an inverter without additional mechanical changes. This approach is intended to shorten design timelines and diversify procurement, allowing customers to use modules from both suppliers without altering inverter specifications.
Fuji Electric and Bosch also plan joint development of application technologies related to cooler design and terminal connections for SiC module integration, and will provide technical support to customers. The initiative aims to enhance supply chain stability and further promote the adoption of electric vehicles.
