Patent attributes
A multi-modal maximum power point tracking optimization solar photovoltaic system is provided. A maximum power point tracking optimizer is connected to and powered by at least one solar cell. The maximum power point tracking optimizer configured to operate: in a pass-through mode when said at least one solar cell voltage is greater than a pass-through threshold and greater than a ratio of the open-circuit voltage of said at least one solar cell, said pass-through mode flowing current through a pass-through circuit; in an optimizing mode when said at least one solar cell voltage is greater than an optimizing threshold and less than a ratio of the open-circuit voltage of said at least one solar cell, said optimizing mode modulating current flow using a DC-to-DC switching circuit to direct the voltage of said at least solar cell towards said ratio of the open-circuit voltage; in an active bypass mode when said at least one solar cell voltage is less than an active bypass threshold, said active bypass mode flowing current through an active bypass circuit.
