The global automotive power electronics market is witnessing strong growth, valued at USD 5.2 billion in 2025 and projected to reach USD 11.5 billion by 2035, expanding at a CAGR of 8.3% during the forecast period. Inverters, DC-DC converters, and AI-based battery management systems have contributed to the global automotive power electronics market as the technologies allow in-real-time optimization of energy, high ratios of power conversion, and increased reliability of electric and hybrid cars.

Johannes Schoiswohl, Head of the GaN Business Line at Infineon, says, Infineon will advance its world-leading position for semiconductor solutions in the automotive industry by bringing GaN power technology to the growing software-defined and electric vehicle market. Our 100 V GaN auto transistor solutions and the upcoming portfolio extension into the high-voltage range are an important milestone in the development of energy-efficient and reliable power transistors for automotive applications.
The global automotive power electronics market is growing at a high rate because of increasing electrification of the vehicles and increasing need of energy-efficient powertrain management. Optimized conversion of energy, better thermal management, and better performance or longer range of electric and hybrid vehicles is being made possible by advanced inverters, DC-DC converters, onboard chargers, and AI-enabled battery management systems that make the use of electric vehicles and hybrids more efficient and reliable.
Power electronics systems based on smart and modular systems and SiC/GaN are enabling the OEMs and suppliers to adopt high-voltage architectures, minimize power losses, and incorporate forecasting energy management functions. For instance, in September 2024, Valeo and ROHM Semiconductor are collaborated to create next-generation SiC power modules to power EV inverters combining mechatronics and semiconductor know-how with enhanced efficiency, thermal capabilities and reliability, enabling wider deployment of electric and hybrid vehicles.
The adjacent opportunities in the market are high-performance EV platforms, scalable power modules, predictive maintenance solutions and energy-efficient subsystems. The Automotive Power Electronics market is changing the automotive ecosystem by offering efficient, reliable and intelligent energy management solutions, that bring forth innovation, vehicle performance and sustainability in the mobility arena in the global mobility sphere.
Automotive Power Electronics Market Dynamics and TrendsRising the trend toward electric and hybrid vehicles is propelling the global automotive power electronics market, since the inverter, DC-DC converters, and battery management systems are essential to managing energy efficiently, increasing the range of vehicles, and making optimal use available on the powertrain.
High prices of silicon carbide (SiC) and gallium nitrite (GaN) devices, high-voltage inverters and high-voltage DC-DC converters, this automotive power electronics solutions are not widely used in cost-sensitive EVs and hybrid vehicles due to the high cost of silicon carbide (SiC) and gallium nitrite (GaN) devices, advanced inverters and high-voltage DC-DC converters.
The automotive power electronics market is experiencing new opportunities as the combination of AI-based energy management, predictive powertrain control, and smart battery systems allow optimizing the EV performance, increasing its battery life, and developing its energy efficiency.
The increased use of >800 V EV platforms is broadly widening the automotive power electronics market as car manufacturers are pursuing increased power efficiency, shorter charging durations as well as the less weight and size powertrain packages.

The inverter dominates the global automotive power electronics because of high energy conversion efficiency, small design, and good support of electric powertrain in EVs, hybrid vehicles, and sophisticated driver-assistance systems (ADAS).
Asia Pacific leads the market because of the high rate of EV adoption, good government incentives on electrification of vehicles, high concentration of automotive power electronics manufacturers and suppliers in China, Japan, South Korea, and India.
The automotive power electronics market is moderately consolidated, and competition is focusing on power semiconductor technologies, wide-bandgap devices (SiC and GaN), power inverters that are highly efficient, onboard chargers, DC-DC converters, and control systems used in electric vehicle powertrain. Infineon Technologies AG, Robert Bosch GmbH, Denso Corporation, STMicroelectronics, and ON Semiconductor Corporation are some of the contributors to the market share size due to the fact that they provide integrated automotive power electronics ecosystems, comprising high-performance power modules, gate drivers, control ICs, sensors, and connectivity solutions, and system-level software platforms.
Infineon Technologies AG is also developing GaN and SiC power transistors, MOSFETs and ICs to enable high-efficiency EV and hybrid powertrains, Robert Bosch GmbH develops power electronics modules, traction inverters, and integrated EV platforms to serve automakers, Denso Corporation is developing vehicle electrification systems, including DC-DC converters and battery management systems, STMicroelectronics is providing power ICs, sensors, and motor-control platforms to automotive traction systems and ON Semiconductor Corporation is also providing power modules.
The creation of power devices that are high-efficiency, system integration, thermal control and real-time optimization of energy is gaining momentum with the government incentives on EV adoption, the increasing demand of electric and hybrid vehicles and collaborations with automakers, Tier-1 suppliers, and semiconductor developers. The interactive competition in such ecosystems augments the differentiation of competitors, allows the mass implementation of EV power systems, and expedites the application of the electric and hybrid vehicle technology, and the global Automotive Power Electronics market is busy to maximize energy efficiency, vehicle behavior, and electrification of mobility systems.
Recent Development and Strategic OverviewIn October 2025, Infineon introduced its first automotive-qualified high efficiency 100 V CoolGaN transistor family (AEC‑Q101), providing samples of this high efficiency GaN power device to power conversion applications in automobiles, including zone control, DC-DC converters, and auxiliary systems to increase the compact and efficient power electronics of EVs and software-defined vehicles.
