Abstract:
"This paper presents the design of a dual-inverter structure for multifrequency power transfer applications in microgrids. The proposed system significantly reduces filtering requirements throughout the microgrid by restricting the multifrequency operation to a specific section of the power distribution line. The dual-inverter device integrates two synchronized full-bridge inverters to enable independent control of voltage and current components at different frequencies. Expanding beyond a single device, a system configuration incorporating two sender/receiver dual-inverter devices enables multifrequency power exchange between nodes in a microgrid. The proposed system is validated through small-signal stability analysis, simulation results, and experimental testing of a demonstrator incorporating the enhancements developed in this work."
