1. An apparatus comprising:
- a power converter having input terminals and output terminals and being operative to convert input power received from a direct current power source at the input terminals to output power at the output terminals; and
a control circuit configured to;
control the power converter to draw the input power according to a maximum power point tracking algorithm; and
while drawing the input power according to the maximum power point tracking algorithm, vary the output power to present, for a first time period, a maximum output power point and to present, for a second time period, a reduced output power point.

Abstract
Controlling a power converter circuit for a direct current (DC) power source is disclosed. The power converter may be operative to convert input power received from the DC power source to an output power and to perform maximum power point tracking of the power source. The power converter is adapted to provide the output power to a load that also performs maximum power point tracking.
