Besaran listrik adalah nilai efektif, nilai rata-rata, nilai puncak, nilai lembah, frekwensi, dan periode. Dalam sehari hari yang sering terde-ngar 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, frekwensi swit-chingnya sama dengan frekwensi jala-jala, sedang frekwensi 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 frekwensi ripple dan frekwensi switching tetap semula. 4. Pada kon-verter DC-DC buck, dengan tegangan luaran yang tetap, maka diper-oleh: makin tinggi frekwensi ripple, dan atau makin tinggi dutycicle, dan atau indutansi makin besar, ripple luaran mengecil. 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 DC-DC 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.

“…[2] To shorten the battery charging time, a DC to DC converter circuit with a high frequency of around 100 Hz is needed using a coil that has a low inductance value. [3] Once the backup battery is fully charged, the PWM pulse width will decrease to near zero. During this stage, the controller will only sense battery voltage.…”

Along with the development of battery/ACCU technology, the ACCU charging and loading system has also developed manually or automatically. In this paper, the results of research on the manufacture of tools that function to monitor and control the charging and loading of electrical power will be explained from batteries that are burdened with lights and DC motors through a control panel or android smart phone with IoT technology. This tool is designed to monitor 2 ACCUs, namely ACCU1 and ACCU2. ACCU1 is loaded with lamp and parallel with DC motor load while ACCU2 is loaded with DC motor and parallel with lamp load. If ACCU1 and ACCU2 are full, ACCU1 is loaded with only one lamp and ACCU2 is only loaded with DC motor. For example, ACCU1's electrical power is still within the limits that can be loaded with lights and DC motors while ACCU2 can't be loaded because electric power is not capable of being loaded with DC motors, the DC motor's load will be transferred to ACCU1. So that ACCU1 is loaded with DC lamps and motors and ACCU2 is charging the electricity, as well as for the opposite condition. The design of this tool uses the main component of the ESP32 microcontroller, where this component has been integrated with the wifi module and other supporting circuit modules, namely the current sensor circuit, voltage sensor and OLED display. The software design consists of a program code designer for hardware using C++ and an android smart phone application design using MIT App Inventor. The results of this study are in accordance with the design specifications, namely the device can be used to control charging and loading as well as monitor ACCU1 and ACCU2 electrical power on OLED screens and on Android smart phones screens
