Abstract

An evaluation is performed for three-phase solar Photo-Voltaic (PV) inverters using either Silicon (Si) or Silicon Carbide (SiC) power devices. Standard and emerging topologies for high-efficiency (>98%) PV inverters are identified and optimized for the capital cost of power filter components and power devices. Analytical formulae are developed for minimum filter inductance considering both current ripple and core-loss constraints. For string-type PV inverters, SiC power devices are shown to be cost competitive compared with Si power devices. Three example PV inverter designs are presented to showcase the use of SiC power devices. Experimental results demonstrate efficiency in excess of 98%.
使用SiC器件的三相太阳能逆变器的评价
对使用硅(Si)或碳化硅(SiC)功率器件的三相太阳能光伏(PV)逆变器进行了评估。针对电力滤波器组件和电力设备的资本成本,确定并优化了用于高效率(>98%)光伏逆变器的标准和新兴拓扑。给出了考虑电流纹波和铁芯损耗约束的最小滤波器电感的解析公式。对于串型光伏逆变器,SiC功率器件与Si功率器件相比具有成本竞争力。本文给出了三个光伏逆变器设计示例,以展示SiC功率器件的使用。实验结果表明,效率超过98%。
