Switching coordination of distributed dc-dc converters for highly efficient photovoltaic power plants

Patent Agamy, Mohammed; Elasser, Ahmed; Sabate, Juan Antonio; ...

A distributed photovoltaic (PV) power plant includes a plurality of distributed dc-dc converters. The dc-dc converters are configured to switch in coordination with one another such that at least one dc-dc converter transfers power to a common dc-bus based upon the total system power available from one or more corresponding strings of PV modules. Due to the coordinated switching of the dc-dc converters, each dc-dc converter transferring power to the common dc-bus continues to operate within its optimal efficiency range as well as to optimize the maximum power point tracking in order to increase the energy yield of the PVmore » power plant.« less
