Abstract :
This paper deals with energy conversion efficiency improvement of solar power application systems. In order to extensively use solar power generation system in all aspects of lifestyle, including moving vehicles, efficiency tracking control systems are necessary for solar power condition change. In this paper, the authors have proposed two kinds of efficiency tracking system: one is the feedforward type which sets a new condition point according to the change of energy (QF1-method); and the other is a robust efficiency tracking system useful for parameter changes in solar panels, which consists of QF1 and a feedback learning system like the peak climbing method (QF2 method). Experimental results show the effectiveness of their proposal
