Electric car maker Ampere, formed by Renault and STMicroelectronics, has announced an agreement starting in 2026 between the two companies on the supply of silicon carbide (SiC) power modules as part of their collaboration on the Powerbox Ampere electric power inverter.
The power box is designed to achieve the best performance-to-size ratio across the Ampere range, and supports both 400V and 800V architectures.
The power box combines three SiC-based power modules, an excitation module – which provides the electrical excitation needed for the motor or generator to control the magnetic field inside the motor – and a cooling core plate designed to dissipate heat from the back side of the power module, simplifying thermal management and the cooling process.
“By working together, we have been able to optimize and secure the supply of key components for our electric motors, to deliver high-performance electric vehicles with greater range and improved charging time. It is in line with Ampere’s strategy is to master the entire power electronics value chain for its E-Powertrains, leveraging STMicroelectronics’ expertise in power modules.”
