项目摘要
Objectives:The objective of this research is to design a novel high-power, "high-frequency", energy-efficient fuel-cell inverter that is scalable and modular and supports bulk power generation and/or reactive and harmonic compensations. This radical high-frequency topology is based on a novel hybrid modulation scheme, next-generation SiC power devices, and nanocrystalline transformer core. The mechanism for validation is twofold: scaled experimental design for concept validation and analytical design using empirically-validated SiC device models for performance and reliability predictions at high power.Intellectual Merit:Conventional low-frequency high-power inverter needs extremely bulky, expensive, and huge-footprint-space filters and transformer. The proposed polyphase inverter eliminates the need for dc link filters and line-frequency utility transformer. Further, due to i) the unique hybrid modulation (which reduces switching loss), ii) significantly reduced core loss of the nanocrystalline transformer core, and iii) reduced on-state drop (implying lower conduction loss) and reduced device capacitance and reverse recovery (implying reduced switching loss) of SiC high voltage devices, operation of high power inverter is feasible at high efficiency even at high frequency. Broader Impact:The proposed inverter has applications ranging from FutureGen, FACTs, solid-state power station, distributed generation, interconnection of two subgrids operating at different frequencies, electric ship, fuel-cell APU for aerospace, to high power UPS. Results of the research will be integrated into two power courses, which are taught by the PI and taken by several students. The project will support 1 Ph.D. student and will incorporate 6 Sr. Design and undergraduate students (with
目标:本研究的目的是设计一种新型的高功率,“高频”,节能的燃料电池逆变器,可扩展和模块化,并支持批量发电和/或无功和谐波补偿。这种激进的高频拓扑结构是基于一种新的混合调制方案,下一代碳化硅功率器件,和纳米晶体Transformer的核心。验证的机制是双重的:用于概念验证和分析设计的规模实验设计,使用经过验证的SiC器件模型在高功率下的性能和可靠性预测。智能优点:传统的低频大功率逆变器需要非常庞大,昂贵,占地面积巨大的空间滤波器和Transformer。建议的多相逆变器消除了对直流环节滤波器和工频公用事业Transformer的需要。此外,由于i)独特的混合调制(其降低了开关损耗),ii)纳米晶体Transformer芯的显著降低的芯损耗,以及iii)SiC高压器件的降低的导通状态压降(意味着较低的传导损耗)和降低的器件电容和反向恢复(意味着降低的开关损耗),高功率逆变器的操作即使在高频下也可以以高效率进行。更广泛的影响:拟议的逆变器的应用范围从未来发电,FACT,固态发电站,分布式发电,在不同频率下运行的两个子电网的互连,电动船,航空航天燃料电池APU,到大功率UPS。研究结果将被整合到两个电力课程,这是由PI教授,并采取了几个学生。该项目将支持1个博士学位。学生,并将纳入6高级设计和本科生(与
