Abstract

This paper proposes two suitable converter topologies for more electric aircraft (MEA) starter generator application. The commercially available silicon (Si) and silicon carbide (SiC) semiconductor devices are also sourced to fit the given design requirements. Different possible configurations of the evaluated converter topologies are discussed. The rectifier design methodology is presented, considering device loss distribution, converter efficiency, required heatsink thermal resistance, dc-link capacitance sizing, delivered power quality and estimated gravimetric power density. The quantitative evaluations have demonstrated the beneficial needs of driving multilevel converter at higher switching frequency operation using SiC semiconductor technology.

飞机电动起动发电机用100kva SiC功率变换器的设计
本文提出了两种适合多电动飞机起动发电机应用的变换器拓扑结构。市售硅(Si)和碳化硅(SiC)半导体器件的来源也符合给定的设计要求。讨论了评估的转换器拓扑的不同可能配置。提出了整流器的设计方法,考虑器件损耗分布、转换器效率、所需散热器热阻、直流链路电容尺寸、输出功率质量和估计的重量功率密度。定量评价表明,在高开关频率下使用碳化硅半导体技术驱动多电平变换器是有益的。
