Accurate prediction of temperature-dependent ac winding loss effects is crucial in the design
of electrical machinery. Average ac winding loss as a function of operating frequency is …

Proximity and additional eddy-current losses can be difficult to calculate and if there are
parallel paths then there can sometimes be increased losses which can be unexpected. The …

A 1.5 kV, 35 kW, 1 kHz silicon steel core medium-frequency transformer is designed and
prototyped for a 10 kV, 0.5 MW electronic power transformer. This transformer uses 0.18 mm …

This paper presents an investigation into proximity losses in end-windings informed from 3-
