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.
