The S-MIC consists of a forward-type isolated pulsating voltage source cell (I-PVSC) and a SEPIC prime converter that can realize the maximum power point tracking (MPPT) function for each PV/wind source. Due to the semi-isolated configuration, the proposed S-MIC can adopt PV/wind power sources with larger operation voltage difference. In this paper, the operational principle of the proposed S-MIC is explained and the small-signal ac model is developed. Computer simulations and prototype circuit experimental results are presented to verify the performance of the S-MIC. © 2014 IEEE.Maximum power point tracking (MPPT); multi-input converter (MIC); renewable energy; small-signal ac model[SDGs]SDG7Computer simulation; Maximum power point trackers; AC modeling; Hybrid pv/wind power; Maximum Power Point Tracking; Multiinput; Operational principles; Prototype circuits; Pulsating voltage sources; Renewable energies; Power electronicsconference paper10.1109/IPEC.2014.6870014
