Possible core materials and their performances are investigated under high switching frequency operation. Core volume, area, configuration, and market availability are studied to achieve the optimal compact and cost-effective transformer model. Next, transformer winding type, size, placement, and cost are analyzed. These steps will result in a complete transformer electromagnetic design and modelling. Afterwards, a 3D transformer model is created and simulated using a Finite Element Analysis (FEA) tool. ANSYS Maxwell-3D is used to simulate the magnetics, electrostatics, and transients of the designed transformer. This model is integrated with a power electronics circuit in ANSYS Simplorer to make a co-simulation for the entire system. Results obtained will include core maximum flux density, core/copper losses, leakage/magnetizing inductances, windings parasitic capacitances, and input/output voltage, current, and power values. Finally, the systems' overall efficiency is calculated and presented. Country unknown/Code not availablehttps://doi.org/10.1109/ICRERA47325.2019.8996515OSTI-MSA
