This paper deals with a photovoltaic (PV) array fed three-phase seven-level converter grid-tied configuration. The proposed system integrates PV array side to AC grid using minimum DC sources and single-phase transformers. The decoupled controller of the system exhibits active and reactive current controllers with coupling compensation network. A low-frequency switching is implemented using carrier-based pulse width modulation (PWM) technique. The system inherits the advantages of simple controller, single DC source and galvanic isolation. A model of the system is developed and its behavior is simulated in MATLAB/Simulink and validated in real-time using hardware in loop (HIL) platform using OPAL-RT.
