| Summary: | Indonesia is the largest archipelago country in the world, consisting of numerous
remote islands. To meet the electricity needs in these remote islands, a small-scale generation
system is required, such as a photovoltaic power system (PLTS). The electricity generated by
PLTS is in direct current (DC), and a micro-inverter is needed to convert it into alternating
current (AC) for utilization by loads. In this research, a micro-inverter is designed using a non-
isolated multi-stage topology, employing a boost converter as the first stage to step up the
voltage level. The output of the boost converter is then fed into the inverter stage to produce a
sinusoidal waveform that complies with the standards. The inverter is designed using two
modified cuk converters. The modification in the cuk converters involves changing the load
position to achieve higher gain compared to conventional cuk converters. The micro-inverter
is tested using two types of sources: solar panels and an AC voltage source separated by a
rectifier block. The test results indicate that the inverter can produce output voltage according
to SPLN standards, with dimensions of 21.7 cm x 16.2 cm x 7 cm and a power density of 121.91
W/L. |
