Global SiC Inverter Market Share Analysis, Industry Trends & Statistics, and Growth Forecasts 2020 - 2035

Posted On 27-07-2025

• Electrification of Mobility: Growing adoption of electric vehicles (EVs) worldwide is catalyzing demand for efficient inverters based on SiC technology. Major automotive OEMs, such as Tesla and BYD, are increasingly integrating SiC inverter solutions to boost EV range and charging efficiency. In 2023, Infineon Technologies introduced its latest CoolSiC power modules, optimizing inverter efficiency in mainstream electric vehicles, enhancing performance, and reducing energy losses.
• Renewable Energy Expansion: The surge in investments in renewable energy systems, particularly solar and wind, has intensified the need for high-efficiency power conversion. Companies like Delta Electronics and ABB are incorporating SiC inverters into utility-scale solar PV systems, enabling higher frequency operation, compact design, and lower cooling requirements. These advances significantly reduce total cost of ownership and improve grid reliability.

• Integration with Advanced Thermal Management: As the power density of inverters rises, manufacturers are focusing on advanced thermal management. ROHM’s recent SiC modules integrate state-of-the-art cooling technologies, allowing for more compact and reliable designs. This trend is shaping industry standards, particularly in heavy industrial and transportation sectors, where reliability and operational temperature range are critical.
• Partnerships & Vertical Integration: From late 2023, an increasing number of vertical integration strategies among SiC wafer and device manufacturers have been observed. STMicroelectronics entered a strategic partnership with Wolfspeed for SiC substrate supply, ensuring supply chain resilience and driving down costs. Such alliances are crucial amid rising demand and occasional raw material shortages.

• Energy Storage Systems (ESS): The emergence of grid-scale ESS presents considerable opportunity for SiC inverter deployment. Companies like Sungrow and Siemens are integrating SiC-based inverters in large-scale battery energy storage, benefiting from higher energy density, fast switching, and lower system losses.
• Commercial Vehicle Electrification: The push toward electrified public transportation and commercial fleets opens new markets for high-efficiency SiC inverters. BorgWarner, for example, announced a collaboration with OEMs to supply SiC inverter modules for electric trucks and buses, supporting CO2 emissions reduction goals.

• In January 2024, Infineon Technologies announced the release of its new generation CoolSiC™ MOSFET modules, enhancing efficiency and decreasing switching losses for EV and solar inverter applications. The launch includes innovative packaging that drives higher current densities, supporting automotive Tier 1 suppliers and accelerating the adoption of SiC-based drivetrains globally.
• In March 2024, STMicroelectronics formalized a long-term SiC wafer supply agreement with Wolfspeed, securing strategic access to high-quality SiC substrates. This move strengthens ST’s vertical integration aims, reducing supply chain risks and supporting rapid expansion plans across automotive and industrial inverter markets.
• In April 2024, ROHM Semiconductor introduced a high-voltage SiC power module specifically designed for heavy-duty commercial vehicles and grid-scale renewable energy inverters. These new modules deliver up to 98.5% efficiency and meet stringent automotive reliability standards. Several leading European OEMs, including Siemens Mobility, have commenced pilot integrations.
