Abstract

Besaran listrik adalah nilai efektif, nilai rata-rata, nilai puncak, nilai lembah, frekuensi, dan periode. Dalam sehari hari yang sering terdengar adalah istilah AC dan DC, besaran yang banyak dijumpai nilai RMS dan efektif. Nilai RMS dan efektif bagi orang awam tidak me-mahami dan tidak berusaha memahami, bahkan mahasiswa pun ma-sih banyak tidak memahami dan tidak penting untuk dipahami. Oleh karena itu pada penelitian ini peneliti meneliti selisih nilai kedua be-saran itu dan efeknya terhadap besaran lain. Kami menggunakan ana-lisis mathematika, hasil simulasi, kurva, analisis rangkaian. Akhirnya dapat menyimpulkan: 1. Jika nilai RMS sama dengan dengan nilai ra-ta-ratanya, maka besaran DC nyaris tanpa ripple. 2. Semua penyearah yang berasal dari jala-jala satu fasa sampai tiga fasa, frekuensi swit-chingnya sama dengan frekuensi jala-jala, sedang frekuensi ripple di luarannya bisa meningkat tergantung dari rangkaian dan jumlah fasa sumber daya nya. 3. Dengan mengubah rangkaian, dan atau memberi masukan lebih dari 1 yang berbeda fasa, maka akan meningkatkan frekuensi ripple dan frekuensi switching tetap semula. 4. Pada kon-verter DC-DC buck, dengan tegangan luaran yang tetap, maka diper-oleh: makin tinggi frekuensi ripple, dan atau makin tinggi dutycicle, dan atau indutansi makin besar, ripple luaran mengecil.

ABSTRACT

Electricity quantities are effective value, average value, peak value, valley value, frequency, and period. In everyday life, the terms AC and DC are often heard, quantities that are often found in RMS values and are effective. The value of RMS and it is effective for ordinary people do not understand and do not try to understand, even many students still do not understand and it is not important to understand. Therefore, in this study, researchers examined the difference in the values of the two quantities and their effects on other quantities. We use mathematical analysis, simulation results, curves, circuit analysis. Finally, we can conclude: 1. If the RMS value is the same as the average value, then the DC magnitude is almost without ripple. 2. All rectifiers come from single-phase to three-phase grids, the switching frequency is the same as the grid frequency, while the ripple frequency outside can increase depending on the circuit and the number of phases of its power source. 3. By changing the circuit, and or giving more than 1 input that is different in phase, it will increase the ripple frequency and the switching frequency remains the same. 4. In a DCDC buck converter, with a constant output voltage, we get: the higher the ripple frequency, and/or the higher the duty cycle, and/or the larger the inductance, the smaller the output ripple.
