Abstract

Perubahan iklim telah mendorong kemajuan teknologi secara pesat untuk mengurangi emisi CO2. Hal ini terlihat dengan adanya inovasi pada sektor transportasi seperti kendaraan listrik serta teknologi G2V dan V2G. Teknologi tersebut melibatkan konverter DC-DC yakni rangkaian elektronika daya yang mengubah nilai tegangan DC ke tegangan DC dengan nilai keluaran yang berbeda. Jenis konverter yang digunakan umumnya adalah half-bridge bidirectional buck-boost converter. Namun, terdapat kelemahan dalam menggunakan konverter DC konvensional tersebut seperti perolehan tegangan yang rendah dan riak arus yang tinggi. Maka, diperlukan penelitian lebih lanjut untuk pengembangan teknologi konverter yang lebih efisien seperti pengembangan floating interleaved bidirectional buck-boost DC-DC converter. Sistem buck-boost converter digunakan untuk mengonversikan tegangan listrik sehingga sesuai dengan rating sumber dan beban. Konverter menggunakan topologi bidirectional agar listrik dapat mengalir secara dua arah yakni aliran arus V2G dan G2V. Rangkaian floating interleaved bidirectional buck-boost DC-DC converter menerapkan topologi interleaved, sehingga daya listrik memiliki riak arus yang rendah. Selain itu, floating interleaved bidirectional buck-boost DC-DC converter juga dapat meningkatkan perolehan tegangan. Pada tugas akhir ini, akan dilakukan desain dan simulasi dari floating interleaved bidirectional buck-boost DC-DC converter serta analisis dari hasil simulasi tersebut serta bidirectional buck-boost converter konvensional sebagai rangkaian pembanding. Hasil penelitian menujukkan bahwa riak arus floating interleaved bidirectional buck-boost DC-DC converter lebih rendah dan rasio tegangan lebih tinggi dibandingkan bidirectional buck-boost converter konvensional. Efisiensi yang dihasilkan floating interleaved bidirectional buck-boost DC-DC converter adalah sebesar 94.32 % pada mode buck dan 95.75% pada mode boost.

Climate change has pushed rapid technological advances to reduce CO2 emissions. This can be seen by innovations in the transportation sector such as electric vehicles as well as G2V and V2G technology. The technology involves a DC-DC converter, which is a power electronics circuit that converts the DC to DC with different output voltage. Generally, the type of converter that used is a half-bridge bidirectional buck-boost converter. However, there are disadvantages in using those conventional DC converters such as low voltage gain and high current ripples. So, further research is needed for the development of more efficient converter technology like floating interleaved bidirectional buck-boost DC-DC converter. The buck-boost converter system is used to convert the electrical voltage so that it matches the source and load rating. The converter uses a bidirectional topology so that electricity can flow in both directions, namely the flow of V2G and G2V currents. Floating interleaved bidirectional buck-boost DC-DC converter circuit applies an interleaved topology, so that the electrical power has low current ripples. In addition, floating interleaved bidirectional buck-boost DC-DC converter can also improve voltage gain. In this final project, the design and simulation of the floating interleaved bidirectional buck-boost DC-DC converter will be carried out as well as the analysis of the simulation results along with conventional bidirectional buck-boost converter for comparison. The results show that floating bidirectional buck-boost DC-DC converter have lower current ripples and higher voltage ratio is than that of conventional bidirectional buck-boost converters. The efficiency produced by the floating interleaved bidirectional buck-boost DC-DC converter is 94.32% in buck mode and 95.75% in boost mode.
