...Milena Kurzawa; Rafał M. Wojciechowski; Paweł Idziak Purpose The purpose of this work is to develop an improved equivalent circuit model for air-core transformers operating at higher frequencies. By refining the classical Cauer-based representation, this study aims to achieve more accurate...

..., the performance of the parallel-connected SEIGs is pre-determined, using the nested LSA and BSA algorithms. The nodal admittance approach has been used for analysing the combined equivalent circuit of the SEIGs by formulating the objective function and thereby determining the operating frequency...

... and an evolutionary strategy. For the gradient method, an objective function J_R (4) is determined from the measured resistance R(s(k)) and the unknown machine parameters of the T-equivalent circuit X_M, R′₂...
