Abstract
A 30% cost reduction of photovoltaic generation can be brought about, by the investment in a novel, highly efficient maximum power point tracker (MPPT). Such a converter is currently under development, implementing a feedforward output current controller as tracking algorithm. The dc-to-dc converter, typical of a MPPT, exploits the efficient high-frequency operation, associated with zero-transition switching. Thus the output filter only consists of the combination of a storage battery and its cabling. The resulting converter is suitable for integration into standard PV panels during manufacturing. The efficiency of the MPPT is 96% for a range of output powers at a low battery voltage of 12,5V and a component cost of US$21,00.
