Abstract: A PV-Boost converter system working at hysteresis MPPT mode of operation is proposed in the present paper. A computer model of the system is developed and simulated. Behavioural parameterised PSpice macromodels are developed for the single photovoltaic element, for series connection of single cells and for PV panel. The PV model is used to simulate a concrete electrical circuit, which optimises the mode of operation of the Boost converter in order to achieve maximum transmitted power from the photovoltaic element (maximum power point tracking – MPPT). The computer models are realised in the Cadence Capture and Cadence PSpice environment.

Keywords: photovoltaic elements; PV boost converters; maximum power point tracking; PSpice models; hysteresis; modelling; simulation.
