Peak Power Tracker Application
The peak power tracker is a customer-provided application. In this application, the load is constantly searching for the
maximum power point of the I-V curve. To achieve this the peak power tracker sweeps around the peak power point. The
Agilent SAS can be used in this application in either Simulator mode or in Table mode. Note that the ability of the Agilent
SAS to track the I-V curve depends on both the excursion from the peak power point and the modulation frequency.
The following graph depicts the Agilent SAS peak power tracking error for both models. The load is sinusoidally swept
from
-5%, -10%, or -15% on one side of Pmp to -5%, -10% or -15% on the other side of Pmp. As the frequency of the sweep is
increased, the tracking error will increase as indicated by the graph.
