摘要: 以五电平有源中点箝位ANPC高压变频调速系统为研究对象，在介绍ANPC五电平拓扑数学模型和PWM调制方法的基础上，对系统开关损耗、电容损耗以及传导损耗进行了量化分析。分析结果表明，ANPC五电平拓扑虽然损耗构成种类更多，但其在开关损耗抑制方面优势显著，可使变频调速系统整体运行效率更高。

Abstract: Taking frequency-conversion speed-regulation system of high-voltage five-level active neutral point clamped ANPC as a research object, switching loss, capacitance loss and transmission loss of the system were carried on quantitative analysis on the basis of introducing mathematical topology model of ANPC five-level and PWM modulation method. The analysis results show that although loss type of the ANPC five-level topology is more, but it has significant advantage in controlling switching loss, and can make the frequency-conversion speed-regulation system of motor have more efficient operation.
