Circular Power Electronics for Green Transition

Power electronics are key enabling technology for high-efficiency energy conversion. In recent years, the massive deployment of power electronic systems in automotive, photovoltaic and wind turbine systems raise concern regarding material usage and e-waste issues. To enhance the circularity impact, the aspects of recycling and remanufacturing need to be considered during the design. The main challenge is to maintain high performance while enhancing circularity impact, as the two aspects often conflict with one another, and the design trade-off need to be addressed.
This project will first develop models for quantifying the impact of the design parameters on the recycling and remanufacturing capabilities of the power electronic systems starting from material property in the components to the system integration design. The established models will then be integrated into the design framework based on a digital twin and demonstrated with a proof-of-concept for validation.
