DOI: 10.1109/tpel.2017.2777604
Abstract: Input-parallel output-parallel (IPOP) nonisolated converters, including dc/dc and dc/ac converters, are effective solutions to increase the power rating and to improve the reliability of the system. For the safe and steady operation of these IPOP… read more here.
