In isolated converter, there is a transformer for voltage amplification and galvanic isolation between source and load. There are mainly two types of converters, isolated and non-isolated. Hence, in this context a DC-DC converter can be employedas a midway stage joining PV panel and inverter to step up the PV voltage. i.e., The maximum power point voltage of a single PV module limits from 15V to 40V DC which is a low value when compared to that of input voltage of inverters in case of single phase AC supply. However, the output from photovoltaic (PV) panel is very low in order to feed the load. Among various renewables, solar energy has a dominant role due to its abundance, a v a i l a b i l i t y o f l e s s power, no wear and tear, clean maintenance and so on. These days, because of impact of environmental pollution and energy crisis, renewable ene rgy sources have been increasingly developed.
