| 摘 要： | 三电平中压变频器有许多优点,但在国内的竞争中却屡屡败于H桥级联变频器,主要的原因是输出电压达不到6 kV(不满足国标要求)和dV/dt高(需要加强绝缘),导致电动机特殊.如何在三电平技术的基础上提高逆变器额定输出电压到6 kV是一个困扰开发三电平变频器技术人员多年的难题.在回顾现有解决方案基础上,介绍一个新方法--定子...

| Abstract: | Three-level medium-voltage inverters have many advantages,but lose competitions with cascaded H-bridge inverters often in China.The main reason is that the rated voltage of this kind of inverters can not reach 6 kV(does not meet the requirement of Chinese standard) and its dV/dt is high(asking for higher level isolation),which make motor nonstandard.How to increase inverter rated voltage up to 6 kV based on three-level technology is a problem which is puzzled engineers for a long time.Based on a review of e... |
