Diode Rectifiers - UNLV
www.egr.unlv.edu• Inrush resistance R inrush is sometimes needed to limit the initial inrush current to a value below that of the diodes. It is usually placed on the DC side, then shorted out afterwards. • In many cases, R inrush is not needed if the Equivalent Series Resistance of the capacitor and cable/transformer wire resistance are sufficiently large.

article.sciencepublishinggroup.com48 S. Jamali Arand et al: Transformer Inrush current mitigation using controlled switching and magnetic flux shunts The most severe case of magnetizing inrush current re-sults from transformer energization. In this case there is a very large change in excitation voltage applied to the core.

Isolation Transformers - Victron Energy
www.victronenergy.comthe neutral output on the secondary side of the transformer, a GFCI will trip or a fuse will blow in case of a short circuit. Soft start is a standard feature of a Victron Energy isolation transformer. It will prevent the shore power fuse from blowing due to the inrush current of the transformer, which would otherwise occur.
PROPER SELECTION OF CONTROL CIRCUIT TRANSFORMERS
