报告摘要：

        Power electronics is ubiquitous in the energy system, nearly 80% of the world’s total electrical power or more than 12 billion kilowatts on average is being processed by power electronics based power converters in every hour of every day. From renewable energy to power supplies, from transport electrification to smart grids, every Watt is converted and controlled by power converters several times from the end to end. In quest of high performance and sustainability of power electronics, we will demonstrate a new design paradigm for power converter systems by means of structural and functional integration with consideration of circularity at the design stage. We introduce a smart control method which exploits electroluminescence from the semiconductor physics to empower a desirable soft-switching control for a significant increase of efficiency. This smart control is, accurate, robust, self-adaptive, and has EMI immunity. Instead of the linear design process using available components, we will cohesively design novel power electronic and passive component packages oriented from the system requirement. The novel packaging design takes new structures, materials, and fabrication/assembling technologies to advance their performance as well as enable their reusability and recyclability for their ‘another life’ and ‘after-life’. New design concept and deliverables enable reusability, repairability, recyclability of most of parts. In consequence, an unprecedented performance is expected, and the circular power electronics is enabled.
