English term or phrase: notching
Definition from NEMA Surge Protection Institute:
A negative or positive change in the wave-shape that repeats cycle to cycle, caused by light peak currents of variable-speed drives or other phase loads.

Example sentence(s):
  • Eliminating voltage notching requires that the source of the notching (commutation) be isolated or buffered from other sensitive equipment using the same distribution system. Rockwell Automation
  • The types of equipment that frequently utilize SCR control schemes and thus experience notching include DC motor speed controls and induction heating equipment. MTE
  • The notching is a normal characteristic of a phase-controlled rectifier but this paper illustrates problems that can occur on systems with low short circuit levels where the voltage notching can excite the natural frequency of the distribution system and cause significant distortion in the supply voltage.

切痕
Definition:
电压切痕是一种持续时间小于0.5周期的周期性电压扰动。电压切痕主要由于电力电子装置在相关的两相间发生瞬时短路时电流从一相转换到另一相而产生的。

Definition from own experience or research:

Example sentence(s):
  • 抑制整流性设备如中频炉、焊机产生的畸变负荷电流,消除电压切痕,确保控制设备正常运行。 - www.fjecw.com  
  • 电压——电源电压越高,意味着电压振幅越大而发射就更多,而低电源电压影响敏感度。 频率——高频产生更多的发射, ... 不要切痕PCB,切痕附近的线迹可能导致不希望的环路 - PCB信息网  
  • 电压切痕(也称为电压缺口)是指一种持续时间小于0.5周波的周期性电压扰动电压切痕 主要是由于电力电子装置在有关两相间发生瞬态短路时,电流从一相转换到另一相而产生 - zjr700214.blog.163.com
