Abstract :
The following paper details out a converter topology which can act as an accumulator of power from different renewable energy sources (RES). Due to the intermittent nature of power availability from RES the DC buses are assumed unregulated. The proposed topology decouples individual voltage sources and reduces unwanted circulation of reactive power between the busses due to mismatch in voltage levels, and at the same time accumulates the power and produces a regulated DC output. The magnetic design of the transformer core has been shown and the topology has been verified with hardware experimental results.
