Silicon Carbide Adoption in UK Power Semiconductor Device Innovation

Introduction

The UK power semiconductor devices market is growing at a fast pace as the need for efficient power conversion and management solutions grows across various sectors. Power semiconductors such as diodes, thyristors, MOSFETs, and insulated-gate bipolar transistors (IGBTs) play a pivotal role in managing electrical energy flow in applications from electric vehicles to industrial equipment and renewable energy systems. Increasing focus on energy efficiency, electrification, and carbon reduction is fueling robust market growth. Technological advances in materials and device design are also making better performance and reliability possible, further accelerating adoption in the UK.

The acceleration of transportation electrification is one of the main growth drivers. The demand for high-performance power semiconductor devices used in motor drives, battery management, and charging infrastructure is being driven by the shift to electric vehicles. In March 2025, Vishay Intertechnology announced a EUR 250 million investment to expand its Newport site in Wales in order to meet this need and improve local capabilities. In addition to generating new jobs, advancing cutting-edge research, and solidifying the UK's place in the global EV semiconductor supply chain, the expansion will greatly increase the production of silicon carbide semiconductors, which are crucial for EV powertrains and enable faster charging, increased energy efficiency, and longer driving ranges.

Renewable Energy Power Generation And Grid Modernization Drive Market Demand

Power semiconductors play a critical role in inverters, converters, and smart grid equipment to enable efficient conversion and management of energy. Industrial automation and robotics also increasingly depend on advanced power semiconductor devices for accurate control and energy conservation. In July 2025, Schneider Electric implemented a GaN-based, large-scale power semiconductor solution across UK industrial automation locations, improving energy efficiency and system reliability. The growth in electric rail transport and energy storage systems in the UK also drives the need for tough and efficient power semiconductor devices. Government policies, such as net-zero emissions targets and investments in electrification programs also spur adoption across industries.

The UK power semiconductor industry consists of design companies, component suppliers, and research organisations with a focus on material science and device development. The university-industry collaboration facilitates new device technologies and manufacturing approaches. Clusters in regions surrounding Cambridge, Bristol, and other technology clusters offer a positive climate for the innovation and manufacturing of power semiconductors.

Future Outlook and Strategic Opportunities

The UK power semiconductor devices market will continue with rapid growth up to 2034, boosted by the electric mobility transition, integration of renewable energy sources, and industrial electrification. Growth opportunities lie in increasing SiC and GaN device manufacturing and creating bespoke power modules for particular applications. Key investments in manufacturing facilities, human capital building, and supply chain robustness will be pivotal to sustaining competitiveness.
