摘要：

The output power of photovoltaic(PV) array depends on solar irradiation levels and ambient temperature. To make full utilization of PV array output power, this paper develops a controller based on AVR Mega16 microcontroller in a PV power system. The controller is used to implement the proposed incremental conductance(IncCond) maximum power point tracking (MPPT) algorithm, which gives a pulse width modulation (PWM) to drive the boost DC/DC converter in the photovoltaic system, and force the photovoltaic module to operate at the maximum power point. The obtained simulation results demonstrate the performance of the proposed MPP-controller. (C) 2012 Published by Elsevier Ltd.
