This article examines models of photovoltaic solar panels, the non-inverting Buck-boost converter. The control strategy of the converter using the MPPT with the PI regulator is presented. The simulation is performed in the PSCAD- EMTDC software. The results show a good performance of the used models and controls. This article can be considered as an update of the models used and a complement in the control of the non- inverting Buck-boost converter.
