TLDR
A single stage converter system that does both dc-dc conversion and dc-ac conversion in one stage for photovoltaic applications and can deliver active power from PV to the grid while continuously tracking maximum power point (MPP).Abstract:
Single stage converter system (SSCS) does both dc-dc conversion and dc-ac conversion in one stage. In this paper, a SSCS for photovoltaic (PV) applications is presented. This system can deliver active power from PV to the grid while continuously tracking maximum power point (MPP). The proposed system is controlled such that it can deliver/receive reactive power from grid. The presented system has several advantages like high gain, low switching loss and compact in size. This system can be used effectively in PV systems, where output voltage of PV is very low. Control scheme of the system along with derivation of control loops is presented. The proposed topology is simulated using MATLAB/SIMULINK, simulation results are presented to validate the proposed idea.read more
