Accurate zero-sequence transformer data is important for correct fault analysis and protection settings. Utilities have been forced to approximate zero-sequence impedances for many three-legged core power transformers in service today that did not un

Phase-shifting transformers are effective elements used to control power flows in many power systems. Their positive influence on power flows has been proved in the literature. However, the efficiency of phase-shifting transformers has not been analy

A network-synthesis procedure for a new low-pass real-to-real (resistance-to-resistance) impedance transformer is presented. Conventionally, the well-known impedance transformer had an all-pole transmission function, and suffered from a theoretical l

In this paper, we propose an approach for integrating a series filter inductance in a coaxially wound transformer (CWT) as a potential alternative to conventional solenoidally wound transformers (SWT) for high-power isolated soft-switching dc–dc co
