A single-phase grid-connected inverter, with unipolar pulse-width modulation, operates from a DC voltage source and is characterized by four modes of operation or states. Two modes take place during the positive load current period and two modes in the negative load current period, as shown in Table 6. Table 6.
Every algorithm for grid-connected inverter operation is based on the estimation or direct measurement of grid-voltage frequency and phase angle. Both parameters are fundamental for correct operation and special care must be taken in their detection to avoid the influence of any external noise.
