Design of a C-core single-phase transformer

This paper addresses design, modeling, and simulation for a C-core single-phase transformer using analytical (MATLAB package). A power rating of 20kVA is assumed while the primary and secondary are separated by a big air-gap of 3mm are used as a case study. Optimum dimensions are selected for such case study to obtain higher performance. Numerical results using finite element analysis are compared with analytical ones to verify the optimum dimensions. These types of transformers are used in applications where power is required to be transferred via big air-gap.
