Losses in laminated non-oriented steel under the effect of two high harmonic clusters, caused by voltage excitation typical of two-level pulse-with-modulated (PWM) DC-link and space-vector modulated (SVM) matrix converters, were analyzed. The predicting method proposed, which incorporates anisotropy of loss K a and grain size g s , describes the magnetizing process within the steel...
Transformers are key elements in power generation, transmission and distribution systems. Transformers under PWM supply are essential elements in industrial applications such as active power line conditioning, electrified railway power systems, PWM DC-DC power converters. Assessing the performance of transformers under PWM supplies is relevant to these applications. In this paper, the variation of...
Iron losses due to flux harmonics in stator cores of pulse-width-modulation [PWM] back-to-back inverter-fed induction motors have a major effect on system efficiency. A new generation of direct AC-AC matrix converters offer important advantages over classical frequency converters such as absence of bulky and temperature sensitive DC-links and possible adjustment of power factor. The paper presents...
