Abstract: A photovoltaic DC power distribution system provides a DC-DC converter having an output serially connected between a photovoltaic module array and a power converter, such as an inverter, in which the input voltage to the power converter is the sum of the voltage from the array and a voltage output of the DC-DC converter. The DC-DC converter only handles a portion of the power transferred from the array to the power converter.
