This paper presents an investigation into proximity losses in end-windings informed from 3-D finite-element analysis of an ac power inductor. The proximity effect in winding conductors is a result of circulating ac currents caused by magnetic fields generated by nearby conductors. The calculated results confirm that the effects within the end-winding while significant are lower compared to those with the active length of the conductors. The common approach of predicting proximity losses using 2… CONTINUE READING
