Comparsion Analysis for Inverter System Based on Si and SiC Power Devices
摘要
Abstract
In the equipment of electric drive and regenerative energy sources,inverter system is a crucial part of them. However,conventional inverter system use Si devices usually,there are high power consumption and low efficiency. In order to solve these problems,SiC devices would be expanded into the inverter,they were constructed of two-level and three-level inverter system based on Si and SiC,the system had carried on the comparison research in power consumption,efficiency,device junction temperature,operation cost and estimated investment returns and so on. Results show that in the power consumption,efficiency and junction temperature,SiC inverter system is obviously better than the Si inverter system;on the initial investment,SiC inverter system is higher,but under the long-term operation costs and benefits are better than Si inverter system.关键词
