A method that can improve the system`s performance is suggested by conducting a structural study of an important passive element inside these pcs. Transformers and reactors are used inside the PCS. This is a study of combining two devices. The advantages of the combination are reducing the weight and volume of the device and increasing the power density. Therefore, the core size optimization was studied to increase the power density of the shared transformer/reactor. The power density can be increased by reducing the core size as the overall device size is minimized, price competitiveness increases. Design variables and constraint conditions were set for optimal design. Optimization was carried out by extracting variable points with the minimum number of points through the DOE method. This was verified through 3D-FEA. It was possible to extract more detailed optimal points and to increase the output density.
