Abstract

This paper analyses and compares experimentally the magnetic hysteresis losses evolution in iron steel sheets submitted to different supplies: sinusoidal, square, triangular, two and three-level PWM voltage waveforms. The magnetic induction amplitude influence and the modulation index are investigated for Two and Three-level PWM voltage waveforms. The experimental investigation is performed using a workbench with a closed loop PWM inverter for imposing the induced voltage waveform on the secondary winding of an Epstein frame.

was born in Santa Catarina (09/05/1973), Brazil. He became Electrical Engineer by the Universidade Federal de Santa Catarina (UFSC) in 1999/2. His M. Sc. degree in Electrical Engineering was received from the same university in 2001 (INEP group). In 2008 he concluded his Doctoral Thesis at this institution (GRUCAD group). His interests include magnetic materials, iron losses, hysteresis models, power electronics and electromagnetic experimentation.

N. Sadowski, Universidade Federal de Santa Catarina, GRUCAD/EEL/CTC, 88040-900, C.P. 476, Florianópolis-SC Brazil

was born in São Bento do Sul (27/03/1959), Brazil. He obtained his Engineer degree at Universidade Federal de Santa Catarina (UFSC) in 1982. He obtained his M.Sc. degree in 1985 at the same university and started teaching at this university as Assistant as well as researching at the newly founded GRUCAD group. In 1989 he started his Ph.D. thesis and finished in 1993 at the Institut National Polytechnique de Toulouse. Returning to Brazil, he continued his research and teaching activities at UFSC and became Full Professor in 1996. In 2000 he obtained the “Habilitation à Diriger des Recherches” (Habilitation) diploma at the Institut National Polytechnique de Toulouse. Prof. Sadowski is author or coauthor of nearly 300 journal articles and conference proceedings. He published with Prof. João Pedro Assumpção Bastos the book “Electromagnetic Modeling by Finite Element Methods” edited by Marcel- Dekker, New York. His research specializes in electrical machines, magnetic materials losses and numerical methods. He has intensive consulting activities with electrical industries in Brazil and foreign.

was born in Santa Catarina (28/11/1964), Brazil. He received the B.E. degree in Electric Engineering by the Federal University of Santa Catarina (UFSC), Brazil in 1992. His M. Sc. degree in Electrical Engineering was received from the same university in 1994. In 2001 he concluded his Doctoral Thesis at this institution. He joined the Department of Electrical Engineering at the UFSC in 2002 and he is now engaged in education and research on Electromagnetic Devices, Electric Machinery, and Electromagnetism. His research interests include magnetic materials, iron losses, hysteresis models, power electronics and electromagnetic experimentation. More specifically, since 1998 his research concentrates on the ferromagnetism characterization and modeling with emphasis on alternating and rotating magnetization of materials.
