Abstract
A non-isolated multiport DC/DC converter topology is provided. The non-isolated multiport DC/DC converter topology is modular and can incorporate an unlimited number of independent input or output ports. The efficiency of the non-isolated multiport DC/DC converter topology is improved through partial power processing techniques without having isolation in the converter. The non-isolated multiport DC/DC converter topology also provides a balanced DC neutral point, making it an ideal candidate for bipolar DC grid or as the front-end of a multilevel DC/AC converter.
