Reactor impedance

Weba gapped iron-core reactor experiencing less severe inrush compared with a transformer. Gapped iron-core reactors can be used as three single-phase units or three-phase units with a three- or five-legged core construction. The five core legs result in a zero-sequence impedance that is equal to the positive-sequence impedance. WebAC Line Reactors vs. DC Link Chokes Introduction This application note is designed to provide an overview of why impedance on the line side of a drive is beneficial in adjustable frequency drives and compares the expected performance of AC line reactors and DC link chokes. In addition, performance testing is presented to provide a harmonic ...
