Load Unbalanced Compensation Method with Artificial Neural Network for Grid-Connected Four-Leg Inverter

This paper proposes unbalanced load compensation (LUC) method with artificial neural network (ANN) for grid-connected four-leg inverter. The proposed method consists of reference calculation and controllers for compensating the unbalanced current for four-leg inverter based on an ANN system. The ANN based calculation and controllers are trained by MATLAB toolbox using Levenberg-Marquardt. The PSIM simulation is provided to validate the effectiveness of the proposed method.
