Method for Maximum Power Point Tracking of Photovoltaic Cells By Power Converters and Power Combiners

This invention relates to a method for Maximum Power Point Tracking (MPPT) a photovoltaic cell by a power converter that provides an output current at voltages useful to operate electronics or charge batteries. This invention also relates to a method for Maximum Power Point Tracking (MPPT) multiple photovoltaic cells by a power combiner that combines the output of the multiple photovoitaic cells into a single output. The power combiner is comprised of multiple power converters, one for each photovoltaic cell. Each power converter used in these methods has an input-regulating element that has an output wave form with a characteristic that is related to the photovoltaic cell voltage and current. As a result only the photovoltaic ceil voltage is directly measured in these methods and the photovoltaic cell current is determined indirectly.
