Abstract
The disclosure relates to technology for providing power, voltage, and/or current from a combination of DC power sources, such as photovoltaic modules or DC batteries. One aspect includes a buck-boost optimizer having a number of inductorless buck stages and a boost stage. The buck-boost optimizer may be used within a power generation system. The combined output voltages of each of the buck stages may be input to the boost stage. The boost stage may have an inductor that may serve as an energy storage device to boost a voltage, as well as to filter a signal from the buck stages. Thus, the buck-boost optimizer may use a single inductor. Having a single inductor provides for a very efficient power generation system. Also, cost and size of components in the power generation system may be reduced.
