Estimation of core loss of transformer under non-sinusoidal voltage supply

Abstract

This paper presents the 1-phase transformer core loss estimation under non-sinusoidal voltage supply. The Epstein test apparatus, with grain oriented magnetic steel side M5 (0.3mm), inverter and low pass filter is used in estimation of core loss. The calculated results will be compared with the measured value and are useful for the appropriate single phase transformer design under non-sinusoidal voltage supply. © 2004 IEEE.
