Simulation of Microcontroller Based Perturb and Observe MPPT Controller for Photovoltaic Energy Applications

摘要

This paper demonstrates the implementation of P&O MPPT controller. The proposed controller was written and compiled in mikroC and later incorporated to a low cost PIC18F4550 microcontroller. Open loop simulation using Proteus Isis was conducted to test the effectiveness of the proposed algorithm. Results obtained from simulation proved the effectiveness of the proposed controller making it suitable for hardware implementation.
