过载电流

In the power supply circuit, series power supply and the adjustment of the series load, the load current flows through all of the adjustments, and transistors Guozainaili worse, once output overload or short circuit, the input voltage increases in the full set of adjustment an emitter, the current surge to adjust the fierce heat, if not over-current protection measures at this time, the adjustment will be burned, power Zhengliuguan also will be greatly threatened or damaged.

中文摘要：在稳压电源电路中，串联型稳压电源的调整管与负载串联，负载电流全部流经调整管，而晶体管的过载能力较差，一旦输出端过载或短路，输入电压全部加在调整管集---射极间，其电流剧增，使调整管猛烈发热，如果此时没有过流保护措施，调整管就要被烧坏，电源整流管也将受到巨大威胁或损坏。

It is the minimum overdrive current required to switch the input from one state to another.

它是最小过载电流必须从一个状态转换到另一个的输入。

Unfortunately, there is inevitably difference in characteristics of the induction motors and converters in a parallel AC drive system, therefore each induction motor as well as converter can not operate at the same working point, some may be overload, some underload.

并联着的各个交流调速系统的负载是不均衡的，这是因为逆变器所带的负载—异步电动机参数及特性不可避免地存在差异，两或多台逆变器作为电源，其等效参数也很难一致，各驱动轮径总存在偏差，因此各台逆变器的输出电流和各台异步电动机的定子电流是不相一致的，有的逆变器、异步电动机可能过载，有的还可能欠载。
