  • 摘要:A model to generate the hysteresis loop starting from the fundamental magnetization curve is proposed in this paper. This was imposed by the necessity to improve the results returned by authors' previous studies about the periodical acswitching mode of single-phase transformers. The hysteresis loop generation and tracing procedures are presented in the paper, the last one dealing with a transformer working in acswitching mode, RL and RC loaded (with current or voltage rectifiers in secondary winding). Comparisons between experimentally and theoretically determined primary current waveforms are included in the paper, to prove the correctness of the proposed hysteresis loop model. MathCAD 6.0 was used as mathematical support.
