Current state-of-the-art solutions perform MPPT for a whole system, a string of panels or an individual panel within a PV system. This results in a loss of energy when the optimal operating point varies among different units. In this thesis, the implementation of MPPT on the sub-panel level is presented. This enables increased energy output under mismatched conditions (e.g. due to partial shading) across the system. Three centrally controlled dc-dc buck converters with series connected outputs are implemented and tested. As the maximum power point (MPP) of panel sections may vary, the proposed multiphase converters operate under asymmetric conditions. Therefore, a control technique to minimize the output current ripple under these conditions is mathematically derived and verified through simulations and experimental measurements.","abstract_html":"Maximum power point tracking (MPPT) is an important feature in solar photovoltaic (PV) systems as it increases the energy yield from such systems by optimizing their operating point.
