Abstract

Multi-Port Converters (MPC) have gained considerable attention due to their applications in renewable energy systems. An example of MPC is the Single Inductor Multi-Input Multi-Output (SI-MIMO) converter, which is capable of integrating different power sources to feed multiple output ports with a simple topology. This article proposes to evaluate the performance of the SI-MIMO converter in a 30 kW system fed with two renewable energy sources, consisting of a wind turbine and a Photo-Voltaic (PV) array, to feed three sets of two 5 kW parallel-connected electrolyzers. A control strategy with Maximum Power Point Tracking (MPPT) for the PV generator and power control for the wind turbine is proposed. The simulation results in PLECS software validate the functionality of the SI-MIMO converter and the proposed control strategy, achieving an efficiency of 98.06%.
