This paper provides a proportional-integral (PI) controller and direct-quadrature (DQ) frame transformation-based optimum control method for a three-phase grid-connected inverter. . This example implements the control for a three-phase PV inverter. Such a system can be typically found in small industrial photovoltaic facilities, which are directly connected to the low voltage power grid. The presented system implements a dual-stage conversion structure, using a boost DC/DC. . This study improved the sliding mode control (SMC) technique based on radial basis function (RBF) neural network for three-phase uninterruptible power supply (UPS). In terms of grid synchronization, voltage regulation, and harmonic abatement, the proposed control technique attempts. .
