MEC Based Scaling Laws for a Tape-Wound Transformer with Voltage Regulation and Core Loss Included

In the system level design such as the design of distributed energy resources, it is required to perform system-level optimization. To achieve that without computational burden, the concept of scaling laws is considered. In this paper, an MEC based scaling technique is derived in which transformer size/mass is predicted based upon rated power, specified current density, and frequency. Curve-fitting techniques are used to derive a meta-model for scaled mass and power loss. The meta-model is compared to designs obtained using detailed design code. A strong agreement between the results from the detailed design code and that predicted by the meta-model is achieved.
