There are two inverters. In the first inverter, 5 PV modules are connected in series. In the second inverter, 3 PV modules are connected in series. The output voltage of each PV panel is assumed as 36V and it is constant. By using the two inverters, we like to feed 220 Volt rms at 50Hz load with no third harmonic. Find the delay angle for each inverter 30 points? Show the solution with detail.
