Today solar energy became an important resource of energy generation. But the efficiency of solar system is very low. To increase its efficiency MPPT techniques are used. The main disadvantage of solar system is its variable voltage. And to obtain a stable voltage from solar panels DC-DC converters are used. DC-DC converters are of mainly three types buck, boost and Cuk. This paper presents use of Cuk converter with MPPT technique. Generally buck and boost converters used. But by using Cuk converter the authors can step up or step down the voltage level according to the load requirement.
