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 sentences:
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.

Definition from
Università degli Studi di Cassino:
Il “notching” è un disturbo periodico della tensione causato dal normale funzionamento dei convertitori statici, quando la corrente è commutata da una fase all’altra.
Example sentences:
Il “notching” è un transitorio periodico che si verifica ad ogni ciclo, in conseguenza dei cortocircuiti fase-fase causati dai processi di commutazione nei convertitori ac/dc ed anch’esso non è influenzato dallo stato del neutro. (Politecnico di Bari)
La figura seguente mostra un esempio di “voltage nothcing” causato da un sistema di conversione trifase a sei pulsazioni. I buchi di tensione si verificano in corrispondenza della commutazione di corrente da una fase all’altra. (Università degli Studi di Cassino)
