Multiple-input converters (MICs) and multiple-output (MOCs) are attractive solutions for interfacing various voltage levels. In order to reveal the intrinsic relationships among diverse topologies provide as many viable possible practical applications, this article aims analyze topology construction principles propose a systematic approach derive MICs MOCs. To begin with, general principle of derivation is analyzed according circuit network theory. Inspired by idea design controllable inductor power-flow loops (IPFLs), five types proposed create multiple (MPN) in Then, four basic switching cells synthesis flow diagram optimal procedure provided guide derivation. As one example, family optimized MOCs with characteristics derived from typical Buck converter. Based on analysis continuous conduction mode (CCM) discontinuous (DCM), number magnetic components not increased at all so that they promising candidates applications requiring compact size high integration. Besides, comparison selection also conducted view specifications. Finally, dual-input converter detail experimentally verified demonstrate theoretical results.
