Three-Phase Solar Photovoltaic System

The configuration of the solar power generation system is as shown in Fig. 5.1. In this system sunlight is captured by SPV array. The SPV array is connected a DC – DC converter to increase the voltage level and to operate at the desired current and desired voltage to match the maximum available power from the PV module. This MPPT DC-DC converter is followed by a DC-AC inverter for grid connection or to supply power to the AC loads in stand-alone applications. The grid connected SPV array system is thus composed of the following blocks:

• Solar Photovoltaic Array

• DC-DC Boost Converter and Controller

• DC Link Capacitor

• DC-AC Three Phase Inverter and Controller

• LC Filter

• Transformer

• Grid.
