In residential-scale PV grid connected system applications, a high gain ratio of the DC-DC boost converter is required. High voltage gain is difficult to obtain when using a conventional DC-DC boost converter. Several research have proposed some types of converters to overcome the problem of high voltage gain ratios, but there is one important unresolved problem with input ripple current. Several research have shown the effect of input current ripple that can reduce the power transfer efficiency of PV. <br /> <br /> <br /> <br /> <br /> In this Final Project, a new DC-DC boost topology converter Dahono-5 with the characteristics of high-gain zero-ripple. Dahono-5 DC-DC boost converter is a cascade of multiphase DC-DC boost converters with conventional DC-DC boost converters. This converter can provide solutions for high-gain requirements as well as zero-ripple input current from PV grid connected system applications. Zero-ripple input current can be theoretically obtained at any switching frequency condition. Experiments were carried out with the implementation of Dahono-5 DC-DC boost converter prototype and it can be shown that Dahono-5 boost converter has high-gain and zero- ripple input current. <br />
