Non-linear Dynamic Transformer Modelling and Optimum Control Design of Switched-mode Power Supplies
… based on a low-cost microcontroller. Accurate transformer modelling is a necessary exercise for the study of the yback converters as well as for model-based controller design. Therefore, a non-linear dynamic model, which allows an accurate representation of both linear dynamics and non-linear …

Measurements and finite element modelling of transformer flux with dc and power frequency current
… can disturb the normal operation of power transformers. If large enough, they cause half-cycle saturation of a power transformer’s core which could lead to overheating due to excessive stray flux. Finite element matrix (FEM) modelling software is of considerable use in transformer …

Permeance based modelling, design and optimization of supercapacitor assisted surge absorber (SCASA)
… cores. We first identified coupled-inductor transformer action under contrasting voltage conditions. In predicting the SCASA operation under both 50 Hz AC and transient conditions, a permeance based model is used. Our model highlights non-ideal characteristics of the coupled-inductor such as …

Development of a finite element matrix (fem)three-phase three-limb transformer model for Geomagnetically Induced Currents (GIC) experiments
… material damage to system components like power transformers. In power transformers, GIC impacts are evidenced by part-wave saturation, resulting in transformers experiencing increased presence of odd and even harmonics. The three-phase three-limb (3p3L) transformer has been found to be the most …
