A Single-Phase Grid-Connected Inverter using Phase Control Method

The design of a single-phase grid-connected inverter (GCI) using the phase-control technique is presented here. The circuit has fewer harmonics and a simpler design than traditional GCI technology. The performance of GCI has a direct influence on the entire distributed generation system. The control architecture of GCI must ensure the capability of matching inverter output voltage and frequency with continuously fluctuating grid voltage and frequency. The dynamic sinusoidal pulse width modulation technique (SPWM) has been used to control the power switches of the inverter. The finished design is simulated in MATLAB/SIMULINK to ensure output results.
