Abstract :
This paper introduces a photovoltaic energy controlling system, controlled by a DC-DC converter and a three-phase neural network controlled bi-directional converter realizes the inversion. A current controlling method of tracking the maximum power point and forcing the system to operate close to this point is used. A back propagation neural network is used as a current controller, which has a high performance in response to current and robustness and insensitivity to the parameter changes. Space vector pulse width modulation (SVPWM) technique is used to decrease the switch losses
