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. The proposed of gird connected to single phase inverter is to converts the
solar power to DC using a simple boost converter and then converts it into AC using
a single-phase DC-AC inverter, which is connected to the power grid. A closed loop
simulation of the proposed set- up is modelIed with Maximum Power Point Tracking
(MPPT) and PI controller in MATLAB-Simulink environment. PLL based
synchronization technique to estimate the phase angle (θ) of the grid voltage
synchronize the system in inverter as well as in controller, so we get the result
synchronized with the PWM
