Application of High Gain Zeta Converter For Photovoltaic System

Photovoltaics are generally used to convert solar energy into electrical energy. If the number of photovoltaic module are limited, then the output voltage will be small. In order to connect the inverter to the grid directly without any transformer devices, it requires extra high gain boost converter. In practice, conventional boost converter only able to increase the input voltage about 4 times. Therefore, this research will implement and analyze the performances of integrated quadratic-boost-zeta high gain DC-DC converter for photovoltaic application. The advantage of this converter is having a high ratio voltage conversion with a small duty cycle and requires few components. From the experiment, this converter can convert input voltage from 18 V to 330 V on duty cycle of 65,92%.
