Abstract: In order to synchronizing the parameters of inverter and grid system, control algorithm plays an important role. Control algorithm used to generate PWM pulses. The total harmonic distortion is generated by non-linear loads. The various methods are available for synchronization and reducing total harmonic distortion. One of them SPWM method, it is reliable and easy method and also MATLAB Simulink is used for proposed

Keywords: synchronization, grid, inverter, THD (total harmonic distortion), control algorithm, PWM pulses.
