The nature of losses in ferrites has not been fully revealed yet. To achieve means for further investigation of ferrite core loss due to electric (E) field, we investigated the response of middle and side legs, cut from commercially available PQ core

Besides their magnetic properties, Mn-Zn ferrites are also characterized by appreciable electrical properties. This electro- magnetic nature of Mn-Zn ferrites material properties causes a dimensional resonance to occur in samples. The latter hinders

Low voltage power applications suffer from losses in diode voltage drops. For example, the Lundell car alternator has a low efficiency, partly due to a high-current diode voltage drop of 1.1V, being 2.2V in a bridge configuration, resulting in 15% of
