Abstract
Currently, the need for new renewable energy is getting higher, so the development of equipment in supporting this is increasingly rapid. designing an inverter that has a high output voltage can be done in several ways, namely by developing from the basic topology of the inverter or developing an inverter input side voltage boost DC-DC converter that has a high gain ratio capability or by using a step up transformer as an AC voltage booster, but it is inefficient considering that the step up transformer has a heavy weight, and reduces space. In this research the researchers designed a cascade boost converter as a single-phase inverter power supply. The cascade boost converter is used as a DC voltage increase where the DC high voltage is entered into a single phase inverter as a DC power supply and the inverter converts from DC-AC. Without using a step up transformer as an AC voltage booster. The inverter is combined with an LC filter as a wave filter to make it close to a sinusoidal wave. The simulation results show that the whole system is able to output a voltage of 220VAC RMS with a frequency of 50Hz.
