Abstract

 This paper has been studying two current control techniques for the two stages singlephase grid-tied photovoltaic (PV) inverter. These control techniques are Sinusoidal pulse width modulation
(SPWM) and Hysteresis current. The whole structure of the grid-tied PV inverter has been studied in details
for each of its parts. For comparison between the two techniques, the designed system has been tested under
MATLAB/Simulink environment for different cases such as insolation and load variation. Results found that
the Hysteresis current control method has a simple structure where it does not need PWM block, but it
produces a higher total harmonic distortion (THD) as compared with the SPWM method
