| 摘 要： | 相对于变频调速系统,高频斩波串级调速系统具有节能效率高、结构简单、技术难度小等优点,在交流调速中得到了广泛应用.但和传统串级调速一样,该系统的严重缺点之一是功率因数低,而且随着负载变化和速度的调节,系统功率因数的变化范围很大.所以有必要准确分析计算其功率因数.本文介绍了高频斩波串级调速系统的工作原理,在此基础上提出了一...

| Abstract: | Compared with frequency conversion speed control,high-frequency chopped wave cascade speed control drive system has such advantages as good efficiency on energy saving,simple structure and little technical difficulty,etc.So,it is widely used in AC governing speed field.However,as the traditional cascade speed governing drive,low power factor is the same overt weakness to the high-frequency chopped wave cascade speed control drive system.In addition,the power factor could change in a large range with the spe... |
