| 摘 要： | 针对传统串级调速系统总功率因素低这一主要缺点,论述了其产生的原因。分别分析了一种由八脉冲换流逆变器构成的串级调速系统、一种转子侧加短路开关的串级调速系统、一种新型的三相四线制串级调速系统,分别阐述了它们能提高功率因数的原理。

| Abstract: | The primary defect of general slip energy recovering system is a lower power factor.The cause of lower power factor is discussed.A slip energy recovering system with eight pluses exchanged current inverter,a system with rotor-side shortcircuit switch and a novel three-phase and four-line slip energy recovering system are respectively analyzed.Their principles that power factor is raised are respectively interpreted. |
