Abstract: In this paper, a hybrid PV–wind-source- based multi-port converter focused on a standalone DC system is proposed. The proposed configuration is able to perform simultaneous three-phase AC–DC conversion and DC–DC conversion, ensuring simultaneous power extraction from these combined sources. The proposed converter is a single-stage converter that enhances dependability and eliminates redundant conversion stages with regard to the earlier configurations for the hybrid PV–wind sources. The operational aspects of the proposed converter are depicted, illustrating the regulation of load voltage and load power because of the dynamic output capability of PV–wind sources. Furthermore, the comprehensive control architecture to govern the concurrent conversion operations with the generation of three-phase modulating signals and duty ratio signal in accordance with the load voltage control is elaborated. Additionally, the modified sinusoidal PWM scheme for the proposed converter is elaborated, showing the unification of three-phase modulating signals and duty ratio signal for the generation of PWM pulses which facilitates the simultaneous power conversion processes. Finally, to validate the suitability of the proposed converter, the performance of the converter under various scenarios is investigated through simulation and experimental case studies.
