Renewable energy sources (RESs) is the major source for the electrical energy in our future, the available systems are solar energy, wind, fuel cell etc. from these solar systems is commonly used as it is highly available. This source of energy is used for agricultural and industrial applications. Renewable energy source (RES) is feeding the motor in the agricultural fields, for motor to achieve high efficiency. Motor is designed for higher voltages, but to get higher efficiency in our solar system it must be designed for lower voltages. So, we need to boost lower voltage to higher voltage converter. Various high gain dc-dc converters are in the literature review and high gain quasi Z source converter uses switched capacitors and one extra inductor to get higher voltage gains. This paper mainly presents, integration of the PV system with high gain dc converter along dc ac inverter feeding to an induction motor drive. In order to extract maximum power incremental conductance algorithm is used in the photovoltaic panel. The converter is controlled by closed loop to maintain the output voltage to be constant. A Matlab Simulink models for high gain dc-dc converter drive applications are developed and outputs are obtained.
