斩波频率
1.
The MOSEF may be destroyed by the great transient impact current when the chopping frequency was not considerate.
用软起动方式能降低无刷直流电动机(BLDCM)起动时的平均电流,但瞬时冲击电流仍会在斩波频率选择不当时烧坏晶闸管。
2) Synchronous chopper
同频斩波
4) bifrequency regulator

1.
Introduction was made to the basic principle of active frequency drift(AFD) method, the in? uences to the system operation per- formance discussed on using the method to test island with different chopping fraction size and polarity choosing, and analysis was carried out on AFD method’s test non-detection zone(NDZ).
介绍了有源频率偏移(AFD)法的基本原理,讨论了使用该方法检测孤岛时不同的斩波率大小与极性的选取对系统运行性能的影响,并对AFD法的孤岛检测盲区(NDZ)进行了分析。
6) high frequency chopper
