Abstract :
In this paper, we investigate the possibilities of Pmax control using the neural networks, a back propagation algorithm is used to train a neural network controller, and we also examine the optimal power converter using a step-up chopper circuit to operate the solar cell at an optimal compensated voltage. The proposed step-up MPPT system is studied by simulation and is implemented by using a microprocessor which controls the duty ratio of the IGBT boost converter
