Abstract
A model is derived to estimate the primary-side inductor current of a discontinuous current mode Flyback converter. The model is validated by comparing the current estimated by the model to the current sensed using a sense resistor. The model was applied in a photovoltaic (PV) system which interfaced a PV module to a battery via a Flyback converter in order to charge a 12V lead acid battery. The system successfully controlled power flow from the PV module according to a model-based current perturb and observe (P&O) maximum power point tracking (MPPT) algorithm.
