In the present trend, the usage of photovoltaic power generation keeps on increasing due to non-availability of nonrenewable sources. Nowadays, the generation of solar power is increasing, but the efficiency of Photovoltaic (PV) is less. Generally conventional boost converters are used to increase the voltage of PV, but it’s not widely used due to its high duty ratio, increased voltage stress, switching losses and increased cost of converter. To overcome all the above drawbacks and to improve the system efficiency, different types of inductor coupled dc-dc converters have been considered and merits and demerits of all the type of dc-dc converter is listed in this paper. Among all dc-dc converters, the capacitor clamp inductor coupled dc-dc converter is preferred by most of researchers to improve the overall system performance and reduce the cost of the converter.
