Abstract
With the increase of distributed generation and storage in the electric grid, the need for isolated, bidirectional converters has risen in recent year. Many of these converters are designed to serve multiple sources and loads and contain monolithic transformers specifically designed for the application. This limits the flexibility of the systems, and typically a whole system must be replaced to add additional ports. The proposed concept allows the low-cost expansion of the multi-winding transformer to achieve a configurable, scalable transformer as part of an isolated multiport converter. Design theory and considerations are presented followed by experimental and analytical results.
