Abstract
The diffusion of distributed electric generation sources is a growing phenomenon, encouraged by the changes in the electric energy market and the concerns about gas emission. Microgrids are composed by different types of generators, several loads and power converters necessary to interface all the microgrid components and the microgrid itself with the main AC grid. This paper presents a new flexible power converter capable of changing its topology by means of static switches so that it can provide different conversion functions using the same hardware. This proposal aims to reduce the number of components, enhancing compactness and simplicity, and resulting in lower equipment costs. The proposed converter is conceived for domestic microgrids, is connected to the AC grid and a renewable energy source (RES) and is configurable as a single-input dual-output (SIDO) converter, providing two different DC voltage levels. After showing all the possible configurations of this converter, the analysis focuses on SIDO, deriving its mathematical model and discussing a procedure to design its elements. The controllability of the SIDO is tested via numerical simulations showing good performance even during fast transient conditions.
