Power electronics is a field of engineering that has immense potential to help address many of the world’s pressing energy and technological issues. As a key enabling technology for renewable energy systems, electric vehicles, smart grids, and energy efficient applications, power electronics plays a vital role in developing more sustainable and environmentally friendly solutions. Capstone projects completed by students in power electronics courses allow those students to directly work on and contribute solutions that can have real world impact.
Some areas where power electronics capstone projects could make especially meaningful contributions include renewable energy integration, electric transportation, energy efficient manufacturing, and sustainable infrastructure development. When it comes to renewable energy, power electronics is critical for maximizing the use of intermittent power sources like solar and wind. Capstone projects developing more advanced inverters, flexible AC transmission systems, energy storage solutions, microgrids, and smart solar/wind generation systems could help further the reliability and scalability of renewable deployments globally. This would significantly further worldwide efforts to reduce carbon emissions from the energy sector in the coming decades.
The electrification of transportation is another sector where power electronics capstone work shows promise. Developing more compact, efficient, and affordable electric vehicle drivetrains, on-board chargers, and supporting infrastructure is key to accelerating the adoption of zero-emission vehicles. Capstone teams have opportunities to advance battery management, motor control, wireless and fast charging technology which could accelerate the transition to sustainable transportation networks. Power electronics also enables energy recovery in vehicles through regenerative braking, improving fuel efficiency. Creative capstone initiatives investigating solid state batteries, inductive charging roads, vehicle-to-grid integration and more could move the needle on emissions reductions from personal transport over the long run.
On the industrial side, power electronic systems are essential for implementing energy efficient manufacturing processes and “Industry 4.0.” Capstone projects exploring new motor drive topologies, predictive maintenance techniques leveraging IoT/AI, optimized process control algorithms, and smart microgrid solutions for off-grid industrial zones could help decarbonize energy intensive sectors like cement, steel, and chemicals production worldwide. Even small improvements in system efficiencies propagated on a large scale yield meaningful energy savings and carbon mitigation outcomes. Power electronics also enables flexible “lean” manufacturing through precise motion and robotics control enabled by adjustable speed drives and power supplies.
When considering infrastructure modernization, smart technologies like active network management, condition monitoring for aging grid assets, flexible AC transmission systems (FACTS), and integrated renewable energy-storage microgrids are all power electronics dependent. Capstone contributions in these categories could support upgrading the world’s electricity networks to become more resilient, adaptive, and capable of hosting high shares of renewable energy to power communities globally in a clean, affordable manner. This modernization is important not only for developed economies but also extending access to underserved populations and facilitating economic development.
Additional potential impact areas for power electronics capstone projects include developing networked “smart buildings” capable of demand response, optimizing distributed energy usage; supporting off-grid electrification through micro-hydro or small wind power generation paired with energy storage; enabling more autonomous and efficient “smart cities” through connected street lighting, electric vehicle integration, waste heat recovery and more. Even non-energy applications like medical equipment, communication systems, consumer electronics all benefit from ongoing power electronics advancements which students can help accelerate.
As power electronics permeates every facet of the energy and technological landscape, capstone projects give students hands-on experience developing practical solutions that can directly aid global clean energy and sustainability challenges. Whether integrating more renewable power, accelerating electric vehicles, improving industrial efficiencies, modernizing infrastructure or extending access to underserved communities – with careful project design and execution, the work of power electronics capstone teams has great potential for meaningful contributions and real-world impact on a global scale. Engaging students in projects that leverage their theoretical education to address pressing societal issues can benefit both their development as engineers and the worldwide transition to a more sustainable energy future.
