An integrated power converter architecture for microgrids with renewable energy sources

الملخص EN

The paper deals with structures that allow an intelligent power flows management between the household users, the electric distribution grid and the distributed generation units within micro grids.

Power electronics provide the control and flexibility required by the micro grid concept.

Correctly designed power electronics and controls insure that the micro grid can meet its customers as well as the utility's needs.

In the paper a new high-efficiency integrated power converter architecture for systems with renewable energy sources, in particular photovoltaic, is proposed which structure has as core the new Double Level Boost converter—and also involves a couple of well-known power converter configurations (Buck-Boost converter, Asymmetrical Bridge Rectifier) in its functioning.

The design and architecture of the converter are explained evidencing its effectiveness in terms of energy management.
