摘要：

A number of algorithms have been proposed for the MPPT of PV modules, but the performance of these algorithms depends on the environmental conditions and also on the type of load (resistive and battery). In this paper, a duty cycle modifier is introduced which optimizes the performance of the existing MPPT techniques by modifying the duty cycle obtained from the MPPT algorithm. The duty cycle modifier also takes into account the variation in the output voltage to provide DC link voltage ripple compensation in grid connected PV systems providing a solution to the reliability issues due to the use of electrolytic capacitors.
