Research on a novel three - level ac chopper and voltage controlling method of the flying - capacitor 三电平交流斩波电路及其浮动电容电压控制策略的研究
A stable flying capacitor voltage must be maintained to facilitate the operation of the chopper 在斩波电路的工作过程中，稳定的浮动电容电压是非常重要的。
With the development of modern power electronics , maglev chopper should be perfect incessantly 随着电力电子技术的发展,磁悬浮列车斩波器技术应该能够得到不断的完善。
Cell , etc . using co laser as incentive source has many advantages , and optical modulating is discussed 选用一氧化碳( co )激光器作为激励光源，讨论了co激光器的结构和机械斩波技术。
The rotor position detector also gives speed signal for adjusting phase current , which is often realized by pwm chopper 另外，转子位置检测器还提供转速信号给pwm斩波器，以调节电机的转速。
