Opportunity Snapshot

Automotive Power Semiconductor Market Growth Drivers and Impact Analysis

Electrified Powertrains Raise High-Voltage Semiconductor Content

Electric vehicles necessitate more conversions than traditional internal combustion systems in the form of traction inverters, on-board chargers, DC-DC converters, battery disconnect modules, and thermal pump converters. This means that there will be additional needs for semiconductor devices such as MOSFETs, IGBTs, SiCs, drivers, and protection circuitry. Practically speaking, this translates into more value being attributed to semiconductors per vehicle as well as more time required for their qualification process; hence, encouraging OEMs to sign long-term contracts with their suppliers. Given the coexistence of 400V and 800V systems, suppliers supporting silicon and SiC technologies can cater to both categories of vehicles.

Software-Defined Vehicles Expand Distributed Power Management

Automotive electronics architecture is shifting from a domain-based approach to zonal control, centralized processing, and intelligent power distribution. In the process, the demand for smart high-side switches, power management ICs, diagnostics, and load protection will be higher for body, safety, infotainment, and telematics applications. The effect on the market will include increased use beyond the propulsion system, enabling suppliers to access more than one subsystem within the automobile. Vehicle manufacturers will also save on weight and perform better diagnostic work, enabling integrated systems with embedded fault and functional safety capabilities.

Localized Supply Chains Improve Automotive-Grade Availability

Automotive semiconductor shortage has revealed the vulnerabilities involved in the reliance on tight corridors of supply for qualified devices. Wafer fabrication, packaging, and regionalization initiatives have been the responses of governments and industry. In the case of power semiconductors, it is important to note that qualification, substrate availability, and module assembly need to be aligned to OEM schedules. The result is an evolution from reactive supply to proactive capacity management. Suppliers with regional redundancy, visibility of quality processes, and reliability in automotive applications will have a more secure position in the design cycle.

Automotive Power Semiconductor Market Future Trends

SiC Migration Across Mid-Range Electric Platforms

The Automotive Power Semiconductor Market Trends for Automotive Power Semiconductor suggest that SiC usage will not be restricted to high-end electric cars anymore due to increasing yield rates, advanced packaging technology, and increased prevalence of 800V systems in higher volumes. It is not necessary that mid-market car platforms will adopt SiC on an equal scale, however, its implementation in such key systems as inverters, chargers, and DC-DC converters will help in boosting the charging rate and energy efficiency.

Power ICs Become Central to Zonal Architectures

Vehicle architectures of the future will incorporate smart power ICs for control of loads close to their point of use. With zonal controllers eliminating wire paths, switches, regulators and diagnostics embedded into them will enable real-time control of the loads for lighting, seating, heating, sensors and infotainment. This will favor suppliers that are strong in mixed-signal design as well as have experience in automotive software. The purchasing process itself will shift, since OEMs and tier-1 suppliers will be selecting power semiconductors at the architectural level.

Automotive Power Semiconductor Market Opportunities

Design Wins in 800V Electric Vehicle Programs

Opportunities in Automotive Power Semiconductor Market Predictions lie in 800V platforms for EVs, where the ability to charge quickly and have an efficient inverter becomes an important consideration for buyers. The suppliers could leverage their offerings such as SiC modules, gate drivers, reference designs, and thermal simulation in a package engineering solution targeting the OEM programs. Such opportunities would present themselves in situations where semiconductor suppliers engage early on with Tier 1 suppliers of inverters and chargers.

Integrated Power Solutions for Commercial Fleets

Fleet operations present chances to leverage durable power electronics for availability, predictable maintenance, and energy efficiency. Electrification of light commercial vehicles, delivery trucks, buses, and initial heavy commercial vehicle applications require durable power modules, battery protection, charging ports, and telematics power control. Suppliers have an edge by providing temperature tolerance, diagnostics, and product lifecycle management. Fleet operators consider total cost of operation rather than cost per part, thus manufacturers offering reliable products in high duty cycle environments will see gains from platform agreements and aftermarket services.
