The growing scarcity of power resources tends researchers to find alternate sources to generate electric power. Even though the electric power could be generated from various natural resources, the only all time available resource throughout the year is sun light. The power generation from sun light is called up with the name photovoltaic system, which consists of varying number of photovoltaic cells that stores generated electric power for some time. Generally the deviation between the generated unit of electricity and consumed unit of electricity is higher due to the conduction loss. Similarly there is a conversion loss which is called switching loss present in every electric system. The energy generated from photovoltaic system has to be regulated to provide uninterrupted power supply according to the system to which it has been connected. There are many devices necessary for the conversion and regulation of power supply to the output device. In this research Cuk converter is considered which is a popular and efficient converter being used in the electronic world.
