Performance Analysis of PV system with Quasi Z-Source Switched Inductor/Capacitor Voltage Gain Converter

Solar power plays an important role in renewable energy generation source. The typical output voltage of PV panels is of low order, which cannot be fed to the grid. A range of converters are used for PV applications like buck, boost, buck-boost, zeta, cuk and sepic as per the required yield voltage. The output voltage generated from the PV system needs to be boosted before sending it to the inverter connected with the grid, which can be done by the help of DC-DC boost converter. In this paper, several topology of QZS converter are discussed, which are QZS with SC and ASC/SL-QZS. These converter are simulated in MATLAB Simulink with the PV array as an input source. The performance of these converter are analysed at the different temperature and irradiance. The temperature and irradiance used for the operation are 30 & 40 (in °C) and 500, 750 &1000 (in W/m2) respectively.
