Three-phase PV inverters are generally used for off-grid industrial use or can be designed to produce utility frequency AC for connection to the electrical grid. This PLECS application example model demonstrates a three-phase, two-stage grid-connected solar inverter.
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.
The inverter phase currents are sinusoidal, balanced, and demonstrate stable operation, indicating effective modulation and control strategies. The THD of the inverter current is impressively low at 0.64 %, which ensures reduced power losses, high power quality, and compliance with grid regulations.

The power generation system is comprised of a solar array that provides a steady-state output of 700 VDC, a three-level inverter that has improved waveform quality as compared to a two-level inverter, and an LCL output filter connected to a low voltage 230 Vrms, 50 Hz grid system.
