直流斩波器 meaning in English
dc chopper
direct current chopper
Examples
- A design adding a dc chopper after the triphase rectification was given to reduce the peak of the pulse of voltage , aiming at the characteristics that the magnitude of the rated voltage of permanent magnet synchronous motor ( pmsm ) is far below that of the power supply , also the electric parameters of the devices were given
针对专用永磁同步电机额定电压大大低于电网电压这一特点，为降低电机上承受的峰值脉冲电压，设计了在三相整流之后增加一级直流斩波器并给出了相应的电气参数。 - The detecting techniques of harmful currents , the modulation methods of novel upfc and the balancing control of capacitors voltage on dc link are studied thoroughly . in order to be fit for three - phase four - wire system , the method of balancing control using chopper presented in literature [ 29 ] is mended
分析了零序和负序电流对新型upfc直流侧电容电压的不同影响，对文献[ 29 ]提出的传统upfc的直流侧各电容电压的均衡控制方法进行了仔细研究，提出了采用b型直流斩波器来控制新型upfc的直流侧电容电压的新方法。
