A Maximum Power Point Tracker with Automatic Step Size Tuning Scheme for Photovoltaic Systems

Figure 16

Measured output power, dynamic conductance, static conductance, and duty cycle waveforms of a PV module array using the variable step size INC method under irradiation that dropped from 1,000 W/m2 to 700 W/m2 and then increased back up to 1,000 W/m2.
