Fig. 20, Fig. 21, Fig. 22 and Fig. 23 show the output power curves under S = 1000 W/m2 and Vbus = 18 V conditions. According to these figures, interphase can be seen that the values of Pomax are all approximately equal to corresponding values of Pomp and the errors between them are always less than 2 W. Therefore, a conclusion can be made that, through using proposed MPPT strategy, PV system can always operate around its MPP well under various T and invariable S,Vbus conditions.
