Abstract
Official abstract text for this publication.
Consistent with an example embodiment, a method of tracking a maximum power point (MPP) of a PV (photovoltaic) system comprises a circuit with a controller controlling a DC voltage-DC voltage converter for converting an output current of the PV system; the controller further comprises a memory. The method comprises measuring a first value of a PV system voltage at an initial MPP; storing said first value in said memory; periodically sampling a power output level of said PV system, and upon detecting a change in said power output level exceeding a first threshold, reading the first value from the memory; and adjusting a duty cycle of the DC voltage-DC voltage converter until the circuit voltage matches said first value; the method further comprising fine-tuning the duty cycle of the DC voltage-DC voltage converter to a further MPP following detecting a change in said power output level exceeding a first threshold.
