Bhawiko, Alekhin Muhammad Azhar (2021) Desain Dan Analisis Buck Converter Untuk Duty Cycle Dan Beban Bervariasi Pada Plts. Sarjana thesis, Universitas Brawijaya.
Abstract
Buck converter adalah salah satu DC-DC converter yang dapat menurunkan tegangan sehingga menghasilkan keluaran yang lebih kecil dari masukannya. Konverter ini banyak digunakan pada sistem charging baterai dimana membutuhkan tegangan keluaran yang lebih kecil dari tegangan masukannya. Pada penelitian ini mengkaji tentang analisis perbandingan unjuk kerja buck converter yang dirancang untuk mampu menyesuaikan tegangan keluaran terhadap nilai duty cycle dan beban bervariasi secara adaptif. Tujuan dilakukan pengujian terhadap buck converter adalah untuk meneliti, merancang, membangun sebuah buck konverter agar sesuai dengan prinsip kerja nya dan dapat bekerja dengan baik pada duty cycle dan beban bervariasi. Pengujian pada buck converter meliputi pengujian tegangan keluaran pada beberapa perubahan nilai duty cycle dan beban, menggunakan PWM dengan frekuensi 20KHz. Rangkaian buck converter sudah dirancang melalui perhitungan parameter komponen untuk menghasilkan buck converter yang dapat bekerja sebagai sistem pengecasan baterai pada PLTS (Pembangkit Listrik Tenaga Surya). Berdasarkan hasil pengujian dan analisis yang telah dilakukan, diperoleh kesimpulan bahwa perubahan nilai duty cycle dan beban pada buck converter mempengaruhi tegangan keluaran yang akan semakin tinggi jika kedua parameter itu ditingkatkan.
English Abstract
Buck converter is a DC-DC converter that can lower the voltage so that it produces an output that is smaller than the input. This converter is widely used in battery charging systems where the output voltage is smaller than the input voltage. The buck converter circuit consists of a MOSFET as an electronic switch, then there is a diode that functions to distribute or disconnect the voltage when the switch is on or off, then there are two passive components, namely capacitors and inductors. To design a buck converter system, it is necessary to calculate the component parameters of the buck converter in order to obtain the inductor and capacitor values used to reduce the voltage as expected. To make research in the form of system simulation, it is necessary to design a buck converter system by making it in MATLAB Simulink software using component parameters that have been calculated previously. After running the simulations according to the calculation, the buck converter can be implemented for testing. This study examines the comparative analysis of the performance of the buck converter which is designed to be able to adjust the output voltage to the value of the duty cycle and varying loads. The purpose of testing the buck converter is to research, design, build a buck converter so that it can run according to its working principle and can work well on varying duty cycle and loads conditions. Tests on the buck converter include testing the output voltage at several changes in the value of the duty cycle and load, using PWM with a frequency of 20 KHz. Based on the results of the tests and analyzes, it is concluded that changes in the value of the duty cycle and load on the buck converter affect the output voltage produced. It will be higher if both parameters are increased.
