نویسنده
چکیده
The present work describes the analysis, modeling and control of an interleaved Boost converters and Buck power inverter used as a DC-DC and DC-AC power conditioning stage for grid-connected photovoltaic (PV) systems. To maximize the steady-state input-output energy transfer ratio a backstepping controller is designed to assure output unity power factor and a Maximum Power Point Tracking (MPPT) algorithm to optimize the PV energy extraction. The achievement of the DC-AC conversion at unity power factor and the efficient PV’s energy extraction are validated with simulation results.
