Abstract

A new multiple-input hybrid energy conversion topology is presented. The proposed topology is capable of combining different energy sources with different voltage- current characteristics, while achieving low part number and bidirectional operational. Compare to previous multiple-input buck-boost converter, the proposed topology provides positive output voltage; it is capable of bi-directional operation; and it has the capability of operating in buck, boost, and buck-boost modes. A fixed frequency switching strategy is considered and analytical analyses as well as detailed device level simulation results are presented.
