Abstract

The output of solar array is changed non-linearly by variation of insolation and temperature. Hence, as varying insolation and temperature, Maximum Power Point Tracking(WPPT) is necessary to increase generation efficiency of solar array. This paper presented WPPT algorithm using position control of output voltage and current of solar array and implemented hardware MPP tracker which is appropriate and inexpensive for low power system$(tens\~hundreds\;watt)$. Finally, those were verified through simulation.
