Interest of square voltages for Solid State Transformer operation with Grain Oriented Electrical Steel wound core

Résumé

This paper presents a comparison between core losses within Grain Oriented Electrical Steel (GOES) wound core, under sinusoidal and rectangular voltage excitations at the same operating frequency and peak flux density. Firstly, results issued by finite elements modeling and measurements are presented and discussed. Secondly, Fourier series are used to calculate the losses induced by the square voltage by adding the contribution of its harmonics, then compared to the sinusoidal case. The different approaches show that for the same operating frequency and induction, the losses under square excitation are lower than the sinusoidal one, this result is the main topic of this paper.
