The renewable energy sources such as fuel cells, PV cells or energy storage devices such as super capacitors or batteries deliver output voltage at the range of around 12V to 70V DC. In order to connect them to the grid or to use for three phase load, the voltage level should be adjusted according to the electrical network standards. First of all the voltage should be stepped up to sufficient level at which the DC/AC conversion can be performed to AC mains voltage requirements. Overall performance of the renewable energy system is then affected by the efficiency of step-up DC/DC converters (especially boost converter), which are the key parts in the system power chain. This review is focused on high step-up voltage and high efficiency DC/DC converters with high voltage gain boost converter. A comparison and discussion of different DC/DC step-up topologies will be performed across number of parameters and presented in this paper.
