        Abstract: According to the single phase two stages of isolated photovoltaic grid connected power generation system, this paper designed the preceding stage BOOST circuit and the later stage inverter topology circuit, analyzed the system control, calculated the BOOST circuit and lowpass filter components parameters and built the Simulink simulation circuit in MATLAB. The simulation experiments prove that the two-stage isolated photovoltaic grid connected power generation system output waveform distortion is small. The system meets the requirements of grid connected frequency phase characteristics.
        Key words: two-stage grid connected photovoltaic; system control; inductance calculation; capacitance calculation; Simulink simulation in MATLAB
