Insights
BorgWarner's new double-sided cooled SiC power module enhances EV inverter thermal management for greater efficiency and compact designs.
The double-sided cooled (DSC) 800V SiC power module represents a significant engineering advancement in thermal management for electric vehicle inverters. By extracting heat from both sides of the silicon carbide power switch, this design directly addresses one of the primary constraints limiting inverter performance. The improved thermal management enables either lower junction temperatures, enhancing reliability, or higher current densities, allowing for more compact designs.
Silicon carbide technology itself is critical, offering substantially reduced switching losses compared to traditional silicon, which directly translates to better overall inverter efficiency. The 800V architecture aligns with the industry's shift toward higher voltage systems that support faster charging capabilities while reducing cable weight.
The module's integration flexibility is particularly noteworthy - BorgWarner states it "could be easily integrated into an OEM's own inverter design and naturally will be part of BorgWarner inverters." This dual-path approach provides manufacturing options that could accelerate adoption across different OEM integration strategies.
The multi-level traction inverter with "clean wave technology" suggests reduced harmonic distortion, potentially delivering smoother motor operation, improved efficiency, and reduced electromagnetic interference - all critical factors in powertrain performance.
BorgWarner advances EV component strategy with new inverter technology, showing R&D progress without immediate financial impact.
This technology announcement reinforces BorgWarner's strategic focus on high-value EV components, particularly advanced power electronics for the transitioning automotive market. Inverter technology represents a critical value chain component that directly influences vehicle performance, efficiency, and range - all key differentiation points for EV manufacturers.
The announcement lacks specific performance metrics, production timelines, or customer commitments that would indicate near-term financial impact. However, it demonstrates ongoing R&D investment in next-generation technologies aligned with industry trends toward higher voltage architectures and improved power density.
BorgWarner's flexible approach - offering both complete inverter solutions and power modules that integrate into OEM designs - creates multiple commercialization pathways, though specific adoption timelines remain undefined in this announcement.
The technology's dual focus on "both high-power applications and compact designs for smaller BEVs and hybrids" suggests BorgWarner is positioning to serve the full spectrum of the electrification market rather than specializing in a particular segment. This broad market approach aligns with the company's strategy to remain relevant across various electrification scenarios as the market evolves.

"With the growing adoption of BEVs and hybrids, efficiency and power density are critical for advancing vehicle electrification," said Dr. Stefan Demmerle, President and General Manager of BorgWarner PowerDrive Systems. "Our latest DSC power module technology enhances thermal management and power conversion efficiency, allowing automakers to develop more compact and sustainable solutions."
The DSC power module is a key component of the inverter, responsible for converting direct current from the battery into alternating current for the electric motor. BorgWarner's innovative design extracts heat from both sides of the silicon carbide power switch, significantly improving thermal and thus electrical performance. This enables either lower junction temperatures or higher current densities, leading to greater efficiency and a more compact footprint for inverters. The power module could be easily integrated into an OEM's own inverter design and naturally will be part of BorgWarner inverters. By leveraging next-generation Viper power switch technology and advanced thermal materials, BorgWarner is delivering a solution that supports both high-power applications and compact designs for smaller BEVs and hybrids, contributing to the future of sustainable mobility.
