In this project the design of high gain dc-dc boost converter is used for the solar photovoltaic applications. When the dc input is taken from the solar system, it is provided as an input to the dc-dc boost converter. Since the voltage from the solar system will have many fluctuations and it can’t be directly provided to the load system. So a high gain dc-dc boost converter is used for avoiding the fluctuations and for boosting the voltage. Two MOSFET switches were used in the converter for boosting the voltage. The desired output voltage can be obtained on the load side by using this converter. If there was any low voltage supply on the input side due to changes in weather condition, then the desired voltage cannot be obtained on the load side. At that condition, by varying the duty cycle of the MOSFET switches to less than 0.5 the boosting operation will takes place and the fixed voltage can be obtained on the load side. In this project if 12V is given as an input from the solar panel then it will get boosted to more than ten times and the output voltage of 196V was obtained on the load side.
