Aug 28, 2014 This means that a steel laminated core will transmit a magnetic flux 1500 times higher than that of air. However, once a magnetic flux flows in an exceedingly transformers steel core, 2 kinds of losses occur within the steel. One is named as “eddy current losses" and also the different is named as “hysteresis
Analysis of Hysteresis and Eddy-Current Losses for a Medium-Frequency Transformer in an Isolated DC-DC Converter. Mizuki Nakahara and Keiji Wada. Department of Electrical and Electronics Engineering. Tokyo Metropolitan University, 1-1 Minami Osawa, Hachioji, Tokyo, JAPAN kj-wada@tmu.ac.jp. Abstract-Recently
An energy-loss equation is developed based on the Poynting theorem. The resultant integrals provide a unified viewpoint that is shown to be the same as the classical eddy- current and hysteresis energy formulations. An expression is derived for the eddy- current loss of a thin transformer lamination by assuming that the
help of values obtained from the CRO the losses are calculated. KEYWORDS : Hysteresis losses, Eddy current losses, Epstein frame, Hysteresis loop. I. INTRODUCTION. Designer of the transformer must know the iron losses i.e. the Hysteresis and Eddy current losses of the magnetic material used for the construction of the
When input power is supplied to the primary of transformer, some portion of that power is used to compensate core losses in transformer i.e. Hysteresis loss in transformer and Eddy current loss in transformer core and some portion of the input power is lost as I2R loss and dissipated as heat in the primary and secondary
This paper investigates the interdependence of hysteresis and eddy-current losses in magnetic cores. Based on the results of a numerical model developed for the analysis, the magnetodynamic loss phenomena are found to be distinctly interdependent. Because of the effects of eddy currents on the flux distribution in the

Class Notes 3: Eddy Currents, Surface Impedances and Loss Mechanisms c 2005 James L. Kirtley Jr. 1 Introduction. Losses in electric machines arise from conduction and magnetic hysteresis. Conduction losses are attributed to straightforward transport conduction and to eddy currents. Transport losses are relatively easy
Reasons for core losses. 2. That core loss is sum of hysteresis and eddy current losses. 3. Factors on which hysteresis loss depends. 4. Factors on which eddy current loss depends. 5. Effects of these losses on the performance of magnetic circuit. 6. How to reduce these losses? 7. Energy storing capability in a magnetic
Hysteresis refers to a situation where the magnetic flux lags the increases or decreases in magnetizing force. – Hysteresis loss is energy wasted in the form of heat when alternating current reverses rapidly and molecular dipoles lag the magnetizing force. – For steel and other hard magnetic materials, hysteresis losses are
