A single phase grid connected with a photovoltaic (PV) power system that will provide high
voltage gain with state model analysis for the control of the system has been presented. First the
photovoltaic system is designed and simulated using MATLAB SIMULINK software. The output
voltage of a PV array is comparatively low thus high voltage gain is necessary for grid-connection
and synchronization. The PV system has been provided with a boost converter which will boost
the low voltage of the PV array to high dc-voltage.
