In designing a grid-connected photovoltaic generator system, a DC-DC converter is needed to increase the photovoltaic output voltage. In designing this converter, a converter with high static gain is usually used in order to increase the photovoltaic output voltage and obtain high conversion efficiency. However, conventional converter has static gain with low output voltage. Conventional converter can only increase the output voltage from the input voltage when the Duty Cycle is 0.75. To meet the high standard of static gain, an output voltage of 2.93 - 3.59 times the input voltage is required. To overcome that problem, the authors propose the use of DC-DC converter topology. Modification on the conventional converter is carried out by adding capacitors and diodes. With the application of this converter, it can be concluded that the output voltage of the converter can be increased for photovoltaic application. © Published under licence by IOP Publishing Ltd.
