Two transformer-based laminated core models, which have the same material and joint type but different leg length, are established, and the joint influence region (JIR) of the core models is proposed to investigate the magnetic flux and iron loss at core joints. In this way the equivalent magnetic path length of the square core can be determined, and the iron loss generated at core joints can be separated from the total core loss. An efficient approach to simulate the iron loss and the flux distributions at core joints is implemented and validated, which can be used in the electromagnetic design of products.
