The power module contains semiconductor switches that convert the battery's DC voltage into AC power for the electric motor. Its electrical and thermal performance directly influences inverter efficiency, power density and driving performance.

Silicon Carbide (SiC) power modules enable higher switching speeds, greater efficiency and improved performance, making them ideal for high-performance electric drives. Silicon (Si) power modules provide a cost-effective solution for many hybrid and secondary drive applications. Magna's standardized platform supports both technologies with a common inverter architecture.

Power modules influence switching losses, thermal behavior and electrical performance inside the inverter. Optimized designs with low stray inductance and efficient heat management help increase overall inverter efficiency while reducing energy losses.

Yes. Magna Power Modules feature a standardized footprint that allows OEMs to integrate either Si or SiC power modules within the same inverter platform. This simplifies development, increases component reuse and reduces engineering and manufacturing costs.

A scalable power module architecture helps reduce inverter costs by enabling common hardware across multiple vehicle programs, simplifying manufacturing and supporting the reuse of key components such as PCBs and busbars.

A semiconductor-agnostic design gives OEMs greater sourcing flexibility and reduces supply chain risks. It also allows manufacturers to adapt to changing market conditions without redesigning the complete inverter system.

The ideal power module depends on the vehicle's performance and cost targets. SiC is typically preferred for maximum efficiency and high-performance electric drives, while Si offers a cost-efficient solution for many hybrid and secondary drive applications. Magna's modular platform allows OEMs to select the technology that best fits each vehicle program.

Emerging innovations such as GaN for all voltage levels, multilevel inverter topologies, high-voltage embedding and integrated power electronics are shaping the future of inverter technology. At Magna, we continuously evaluate these developments and evolving OEM requirements to help address future electrification needs.
