脉动电压 meaning in Chinese

pulsating pressure
pulsating voltage
ripple voltage
voltage, ripple

The 7 years ' applicable practices indicate that the frequency modulation technology with dc bus voltage ripples is very effective to suppress acoustic resonances
7年的使用实践表明，直流脉动电压频率调制技术对抑制声谐振现象十分有效。
With an aim at this problem , this paper suggests the modulation scheme with dc bus voltage ripple by using the front - end active power factor correct circuit based on the analysis of necessary conditions of producing acoustic resonances
针对这一现象，在分析产生声谐振的必要条件的基础上，重点提出了利用前级有源功率因数校正电路的直流母线脉动电压的调制方案。
