Abstract

Konverter DC ke DC merupakan peralatan yang menghasilkan tegangan atau arus DC yang berasal dari suatu sumber DC. Konverter DC ke DC umumnya berfungsi untuk menaikkan atau menurunkan tegangan atau arus DC. Konverter DC ke DC memiliki banyak jenis salah satunya adalah rangkaian DC-DC Interleaved Buck Converter Konvensional. Akan tetapi, rangkaian DC-DC Interleaved Buck Converter Konvensional memiliki banyak kekurangan antara lain, rasio konversi penurunan tegangan DC yang rendah serta memiliki rugi-rugi pensaklaran yang tinggi. Oleh karena itu, dikembangkanlah rangkaian DC-DC Interleaved Buck Converter dengan Kapasitor Kopling.Dalam Tugas Akhir ini akan dirancang dan diimplementasikan rangkaian DC-DC Interleaved Buck Converter dengan Kapasitor Kopling. Rangkaian DC-DC Interleaved Buck Converter dengan Kapasitor Kopling memiliki fungsi yang sama dengan rangkaian DC- DC Interleaved Buck Converter Konvensional. Akan tetapi, memiliki rasio konversi penurunan tegangan DC yang tinggi serta rugi-rugi pensaklaran yang rendah. Sehingga, rangkaian DC-DC Interleaved Buck Converter dengan Kapasitor Kopling memiliki efisiensi yang tinggi. Hasil implementasi menunjukkan bahwa rangkaian DC-DC Interleaved Buck Converter dengan Kapasitor Kopling memiliki efisiensi sebesar 88.31% pada tegangan masukan 60 V dan tegangan keluaran 12 V. Selain itu, rasio konversi penurunan tegangannya juga dua kali lebih rendah, dimana untuk tegangan masukan 60 V dan duty cycle 40% diperoleh tegangan keluaran sebesar 11.5 V.

DC to DC converters are devices that produce DC voltage or DC current that come from a DC source. DC to DC converters are generally used to raise or lower the DC voltage or current. DC to DC converters have many types one of which is a Conventional Interleaved Buck DC- DC Converter. However, a Conventional Interleaved Buck DC-DC Converter has many weakness, among others, the conversion ratio of the DC voltage is low and switching losses are high. Therefore, it is developing an Interleaved Buck DC-DC Converter with Coupling Capacitors. This final project design and implement an Interleaved Buck DC- DC Converter with Coupling Capacitor. The Interleaved Buck DC-DC Converter with coupling capacitor has a similar function with the Conventional Interleaved Buck DC-DC Converter. However, the conversion ratio is high and switching losses low. Thus, an Interleaved Buck DC-DC Converter with coupling capacitors have high efficiency.The results show that the implementation of an Interleaved Buck DC-DC Converter with coupling capacitor has efficiency around 88.31% at 60 V input voltage and 12 V output voltage. In addition, the conversion ratio is two times lower than Conventional Interleaved Buck DC-DC Converter, which in 60 V input voltage and 40% duty cycle are obtained 11.5 V output voltage.
