It is formed based on the superposition theorem, orthogonal power flow theory, and frequency selectivity criteria. It is a unique system where different frequency voltages and currents are present on the multifrequency (MF) bus and different frequency powers maintain orthogonality and transmit simultaneously through the MF bus without mixing. Frequency selectivity criteria states that the consumers can choose any available frequency power from the MF bus based on their requirements. This research work focuses on the basic architecture, converters, and control strategies of MFMG.enELECTRONICS AND ELECTRICAL ENGINEERINGThesis
