摘要:
作为第三代半导体材料,SiC 材料在禁带宽度、击穿场强、电子饱和速度、热导率等方面,比第一、二代半导体材料具有明显的优势。为了研究SiC 二极管及混合功率模块在并网光伏逆变器中的应用优势,本文分析了其工作特性并开展了SiC 二极管开关损耗及并网光伏逆变器转化效率的实验测试。结果表明,SiC 二极管的开关损耗远低于Si 二极管的,混合功率模块的恢复能耗大大降低,将其应用于并网光伏逆变器电路中可以有效提高并网光伏逆变器整机效率。
Abstract:
As the third generation of semiconductor materials, Silicon Cabide(SiC) has more obvious advantages than the first and second generation of semiconductor materials, such as forbidden band width, breakdown voltage, electron saturation velocity, thermal conductivity, etc. In order to study the application advantages of SiC diodes and hybrid IGBT modules in photovoltaic inverter, it analyzed the working characteristics and carried out experiments on switching loss of SiC diode and transferring efficiency of grid-connected photovoltaic inverter. Experimental results show that switching loss of the SiC diode is much lower than that of the Silicon diode, which lead to big reduction of hybrid module recovery energy. Application of hybrid module in grid-connect photovoltaic inverter circuit can effectively improve its efficiency.
