摘要: Provided is technology for providing power, voltage, and/or current from a combination of DC power sources, such as photovoltaic modules or batteries. One aspect includes buck-boost optimizer (110) having number inductorless buck stages (104) and boost stage (106). The may be used within generation system. combined output voltages each the input to (106) have an inductor (208) that serve energy storage device well filter signal (104). Thus, use single inductor. Having provides very efficient Also, cost size components in system reduced.
