Design Methodology and Optimization of a Medium Frequency Transformer for High Power DC DC Applications
The medium frequency power transformer (MFPT) is one of the key elements of an isolated bi directional dc dc converters in applications such as future all dc offshore wind farms, traction, and solid state transformers. This paper describes a design methodology taking into account loss calculation, isolation requirements, and thermal management. Incorporating this design methodology, an optimization process with a wide range of parameter variations is applied on a design example to find the highest power density while the efficiency, isolation, thermal, and leakage inductance requirements are all met.
