摘要：The renewable energy sources such as PV modules, fuel cells or energy storage devices such as supercapacitors or batteries deliver output voltage at the range of around 12 to 70 VDC. In order to connect them to the gridthe voltage level should be adjusted according to the electrical network standards in the countries. First of all thevoltage should be stepped up to sufficient level at which the DC/AC conversion can be performed to AC mains voltagerequirements. Overall performance of the renewable energy system is then affected by the efficiency of step-up DC/DCconverters, which are the key parts in the system power chain. This review is focused on high efficiency step-upDC/DC converters with high voltage gain. high step-up ratio dc–dc converters are preferred in renewable energysystems The differentiation is based on the presence or lack of galvanic isolation. A comparison and discussion ofdifferent DC/DC step-up topologies will be performed across number of parameters and presented in this paper.
