The utilization of photovoltaic energy becomes an important source of electrical energy with the advancement in power electronic technology. The dc-dc converters is one of inevitable part of renewable energy system, for connecting the PV panel to the grid or AC load through an inverter. MPPT (Maximum Power Point Tracking) maximizes the power production of the PV panel. The advantages of high step up converters includes improving voltage gain without using extreme duty ratio, reduction of voltage stress, current ripple and conduction losses are desirable for renewable energy applications. The review of various topologies of high step up converter and their performance with voltage multiplier circuits are discussed in the paper. The merits and demerits of these converters are discussed. This paper shows the comparison of efficiency and voltage gain for various boost converter topologies integration with voltage multiplier
