Abstract

In this paper, the validation and performance testing of a control scheme for a single-phase single-stage transformerless grid-connected Photovoltaic (PV) inverter are presented using the Control-Hardware-in-the-Loop (C-HIL) implementation. The control scheme uses the DC-link voltage controller and grid current controller, and it is executed in a LAUNCHXL-F28379D development kit, providing a cost-effective solution compared to commercially available tools. In order to extract the maximum available power from the PV system under different conditions, two Maximum Power Point Tracking (MPPT) algorithms, including the Perturb and Observe (P&O) algorithm and incremental conductance method, are investigated and compared. The simulation and experimental results are provided to verify the performance of the studied control scheme.
