Energi listrik merupakan salah satu kebutuhan pokok dalam menunjang berbagai sektor kegiatan manusia. Namun, dalam realisasinya, PT. PLN menemui kendala seperti terputusnya jalur distribusi listrik ke pelanggan. Untuk mengantisipasi terjadinya pemadaman listrik, maka dibutuhkan peralatan seperti uninterruptible power supply (UPS) sebagai sistem back up supply. Pada penelitian ini, rancangan sistem UPS terdiri dari baterai, boost converter, full-bridge inverter satu fasa, serta filter LC yang digunakan sebagai suplai energi listrik untuk beban induktif dengan kriteria regulasi tegangan dan regulasi harmonisa sesuai standar yang berlaku. Agar sistem dapat dioperasikan secara terintegrasi, maka terdapat kontrol PI dengan nilai Kp yaitu 5 dan Ki yaitu 40 sebagai pengatur tegangan output boost converter sebesar 311 VDC yang diperoleh melalui perhitungan analitik. Adapun rancangan boost converter memiliki kapasitas daya sebesar 720 Watt. Hasil simulasi menunjukkan nilai drop tegangan output maksimum UPS sebesar 3,5 VAC terhadap standar tegangan nominal 220 VAC, serta menghasilkan bentuk gelombang tegangan dan arus output sinusoidal dengan suplai energi listrik maksimum menuju beban sebesar ±463 VA. Electrical energy is one of the basic needs in supporting various sectors of human activity. However, in its realization, PT. PLN encountered problems such as disconnection of electricity distribution lines to customers. To anticipate a power outage, equipment such as an uninterruptible power supply (UPS) is needed as a back up supply system. In this research, the UPS system design consists of a batteries, boost converter, single-phase full-bridge inverter, and an LC filter which is used as an electrical energy supply for inductive loads with the criteria of voltage regulation and harmonic regulation according to applicable standards. In order for the system to be operated in an integrated manner, there is a PI control with a value of Kp is 5 and Ki is 40 as a boost converter output voltage regulator of 311 VDC which is obtained through analytic calculations. The design of boost converter has a power capacity of 720 Watt. The simulation results show the maximum UPS output voltage drop value of 3.5 VAC against the nominal voltage standard of 220 VAC, and produce a sinusoidal output voltage and current waveform with a maximum supply of electrical energy to the load of ± 463 VA.

Sebagai sumber energi terbarukan fotovoltaik berkembang pesat. Fotovoltaik memiliki karakteristik arus dan tegangan non-linier, memiliki nilai daya maksimum pada tegangan optimal, dan bergantung pada kondisi lingkungan seperti suhu dan radiasi. Jadi ada kekhawatiran tentang pasokan listrik yang tidak mencukupi untuk penerangan jalan. Untuk mendapatkan daya maksimum pada setiap iradiasi, diperlukan rangkaian DC-DC converter yang dikendalikan dengan metode pelacakan titik daya maksimum (Maximum Power Point Tracking/MPPT). Oleh karena itu diusulkan MPPT khusus berbasis fuzzy logic. Dengan mengatur mikrokontroler ARM STM32F4 didapatkan duty cycle terbaik pada rangkaian konverter Zeta, sehingga memaksimalkan daya keluaran fotovoltaik dan menghasilkan daya keluaran terbaik. Hasil dari MPPT Fuzzy akan dibandingkan dengan MPPT P&O. Berdasarkan pengujian integrasi secara hardware, MPPT Fuzzy mendapatkan nilai rata – rata akurasi 97.16% terhadap daya maksimal, dan MPPT P&O mendapatkan nilai rata – rata akurasi 91.84% terhadap daya maksimal.

Motor induksi banyak digunakan di industri, namun dalam penggunaannya motor induksi memiliki hal-hal yang kurang menguntungkan seperti nilai overshoot tinggi, settling time lama saat start dan bila terjadi pembebanan kecepatan motor induksi akan turun. Sliding mode control diperkenalkan dengan mengambil keuntungan dari karakteristik switching inverter untuk mengontrol mesin elektrik yang akan menghasilkan overshoot rendah dan settling time yang pendek dengan bentuk transient dan steady state yang baik. Sliding mode control didesain untuk beroperasi melebihi variable yang sama seperti digunakan pada metode DTC. Untuk meningkatkan performa putaran motor induksi pada kondisi ada gangguan, control putaran dengan sliding mode control akan diuraikan, dimana jenis control ini robust pada saat terjadi gangguan dengan variasi parameter dan torsi beban berubah. DTC digunakan sebagai paramater kontrol, untuk mencari torsi, fluks dan sudut yang nantinya akan digunakan sebagai penyulut inverter. Untuk kecepatan diambil dari kecepatan estimator, error dan delta error kecepatan putar sebagai masukan pada SMC. Hasil dari simulasi kondisi berbeban, saat starting overshootnya 83 rad/s, time settlingnya 0.12s dan time risenya 0.02s. Pada kondisi perubahan beban, respon hampir tidak mengalami perubahan kecepatan atau bisa dikatahkan respon kecepatan stabil bila ada gangguan meskipun terdapat osilasi atau ripple.

In this paper, a dual input single output buck converter with fuzzy control is designed and simulated for a DC load supply using the PSIM software. The dual input single output buck converter can work with two different sources. The use of the two power sources of photovoltaic and wind turbine is an alternative solution for obtaining a greater rated power to supply DC loads. The solar panel and the wind turbine will supply the power for the dual input buck converter circuit simultaneously. For the two power sources to work simultaneously, the duty cycle is set using fuzzy control, so that the output voltage can match the desired voltage. Simulation testing is carried out with photovoltaic conditions with varying irradiation and temperature values, as well as varying wind speeds in the wind turbine, i.e, between 4-8 m/s. The simulation results show that the dual-input single-output buck converter can work when powered by two different power sources with a stable output voltage of the converter at its set point, i.e., 14.4 volts.

In a country with a tropical climate, the use of the sunlight is very important. Thus, to be able to apply, a solar power conversion system is needed into a source of electrical energy. The use of electrical equipment that is quite high will increase the consumption of electrical power so that people spend more and more on electricity costs. A battery is a device consisting of electrochemical cells that can store electrical energy. Overcharging the battery causes the battery to be susceptible to damage. So that the process of charging the battery becomes important, to get maximum attention and good efficiency. In this study, the use of solar cells with battery chargers using the CC-CV (Constant Current-Constant Voltage) Fuzzy Control method uses a solar cell to convert sunlight into electrical energy. The specifications of the solar cell used are 100 WP, while the charging process uses a DC-DC Sepic Converter. DC-DC Sepic Converter can increase efficiency and output polarity that is not reversed. This system is used to charge the lead-acid battery of 12 Volt 20 Ah. The charging method used is constant current-constant voltage (CC-CV) using Fuzzy Logic Control to adjust the duty cycle so that the converter output is by the constant current - constant voltage (CC-CV) planning. The constant current - constant voltage (CC-CV) method was chosen because it can provide good efficiency in charging time and the addition of the Constant Voltage method after Constant Current is enabled to keep the voltage at the setpoint and avoid overvoltage during the charging process. Sepic Converter is used to maintain the value of the voltage set point at 14.4 Volts and 6 Ampere for battery charging current.

Implementation of photovoltaics as a renewable energy source is growing rapidly. The cost of implementing photovoltaic is very high therefore it is necessary to control the optimization of the PV. The V-I aspect of solar cells is nonlinear, changing with the intensity of sunlight and the surface temperature of the photovoltaic, causing the output power of the photovoltaic to vary. This research will use the zeta converter as a DC chooper controlled by MPPT based on fuzzy logic controller. Software Power Simulation (PSIM) is used to simulate MPPT. The MPPT fuzzy logic controller will be compared with the MPPT human psychology optimization (HPO). The simulation results show that MPPT fuzzy gets the same accuracy as MPPT HPO and is better than the average accuracy without MPPT which is 99,98%. Then the speed in finding the maximum MPPT fuzzy point gets a better time tracking when compared to the MPPT HPO which is 0,0283 seconds. MPPT fuzzy is able to exceed the maximum power at varying sunlight intensity and temperature.

Lithium-ion batteries have been widely used in energy storage for electric vehicle and hybrid vehicle applications. After several cycles of charging and discharging, there is one cell whose performance and capacity decreases, causing the performance and capacity of the battery pack to decrease so that it cannot work optimally. So it is necessary to design a cell voltage balancing system to minimize cell voltage imbalance in the charging process. Passive balancing is widely implemented because of its simplicity, reliability, and relatively low cost. The balancing process must be carried out as quickly as possible as the battery is charging, so a PWM ignition technique using mamdani fuzzy is needed to discharge an unbalanced battery cell. The result are compared with no balancing system, fixed balancing 50% duty cycle system, and sugeno fuzzy logic balancing system. From the simulation result, using mamdani fuzzy the final delta voltage value is 0.0344 volt, energy charged is 58.18 Wh and the final State of Charge is 74%. When compared with other balancing method, it shows that using mamdani fuzzy logic method is more optimal because the final of delta voltage value is very small and the battery capacity charged is larger than other method.

This paper presents a digital implementation of a brushless direct current motor (BLDCM) drive with a six-step pulse width modulation (PWM) using a programmable simplified C-block based on the STM32 microcontroller. The implementation is conducted through the PSIM simulation platform, which is commonly used for power electronics and motor control. This approach combines the benefits of using a programmable simplified C-block for precise and flexible programming with the PWM concepts of the STM32 microcontroller. The PWM method used on the BLDCM drive is the unipolar upper PWM technique (H~PWM_L~ON). The performance of the PWM implementation is analyzed in detail, including the accuracy of the PWM generation using a Fast Fourier Transform (FFT), the gating of the IGBTs in the three-phase inverter, and the effect of the duty cycle on the BLDCM's speed, phase voltage, and phase current.
