Abstract
Talkative Power Conversion (TPC) is an instance of simultaneous information and power transfer, in which data modulation is integrated in the power conversion process. The TPC framework is generalized in this work to incorporate multiple-input multiple-output (MIMO) processing. In this innovative concept, called MIMO-TPC, power electronic converters with multiple switching units are applied that use coordinated or uncoordinated, data-dependent switching patterns in order to increase the degrees of freedom for data modulation. A selection of power converter topologies is investigated that fit within the framework of MIMO-TPC, including H-bridge DC/DC converters, multi-phase DC/DC converters, multi-phase DC/AC inverters, multi-input converters, multi-modular converters, multi-level converters, and multi-port converters. These switched-mode converter classes are characterized by an elementary building block and elementary combinations. Encouraging advantages of MIMO-TPC are elaborated, potential applications of MIMO-TPC are discussed, and open challenges as well as future research directions are suggested.
