Abstract—This work presents a simple and low-cost powerelectronic system that allows a flexible control of the operatingconditions of the photovoltaic module. The system consists of abuck converter with sliding mode control. Control algorithmsfor maximum power tracking, module voltage and load currentregulation are proposed. Moreover, these algorithms can bereadily combined to have a complete control of the energyconversion system. The dynamic analysis reveals that theremay be regions of instability that are avoided by appropriateswitching logics. Operation and main features of the proposedelectronic power controller are validated through simulation andexperimental results.
