Abstract

Abstrak–-PMSG (Generator Sinkron Magnet Permanen) adalah generator yang medan magnetnya dibangkitkan oleh magnet permanen yang terletak pada rotor dan tidak memerlukan sumber eksitasi eksternal untuk membangkitkan medan magnet. Meskipun mesin magnet permanen adalah mesin listrik berperforma tinggi, ada komponen torsi yang mempengaruhi kinerja keluarannya yang disebut torsi cogging. Torsi cogging juga menciptakan riak torsi selama operasi yang juga menyebabkan kerugian lain seperti berkurangnya efisiensi, kebisingan, dan getaran pada sistem. Untuk mengatasi masalah tersebut, penelitian ini menawarkan metode step skewing. Tujuan dari metode ini adalah untuk mengurangi nilai perubahan reluktansi terhadap posisi. Dengan demikian, perubahan desain dimensi aksial rotor akan mengurangi nilai perubahan reluktansi dalam arah keliling dan dengan demikian torsi cogging akan berkurang. Tujuan dari penelitian ini adalah untuk menguji pengaruh metode step-skewing dalam menurunkan torsi cogging pada generator sinkron magnet permanen. Metode yang digunakan adalah simulasi 3D dengan menggunakan software berbasis finiteelement method (FEM). Pada simulasi metode step skewing ini, parameter yang divariasikan adalah jumlah segmen magnetik (j) sebesar 3, 4, 5, 6, dan 7. Hasil simulasi dan analisis menunjukkan bahwa metode step-skewing dapat mengurangi nilai torsi cogging pada generator sinkron magnet permanen. Semakin besar jumlah segmen magnetik (j), semakin kecil nilai torsi cogging.Kata Kunci— Cogging, Segmen, Skewing, PMSG.Abstract—PMSG (Permanent Magnet Synchronous Generator) is a generator whose magnetic field is generated by a permanent magnet located on the rotor and does not require an external excitation source to generate a magnetic field. Although permanent magnet machines are high performance electric machines, there is a torque component that affects their output performance called cogging torque. Cogging torque also creates torque ripple during operation which also causes other disadvantages such as reduced efficiency, noise, and vibration in the system. To overcome this problem, this research offers a step skewing method. The purpose of this method is to reduce the value of the change in reluctance with respect to position. Thus, a change in the design of the axial dimension of the rotor will reduce the value of the change in reluctance in the circumferential direction and thus the cogging torque will be reduced. The purpose of this study is to examine the effect of the step-skewing method in reducing the cogging torque on a permanent magnet synchronous generator. The method used is 3D simulation using finite-element method (FEM) based software. In this simulation of the step skewing method, the parameters that are varied are the number of magnetic segments(j) of 3, 4, 5, 6, and 7. The results of the simulation and analysis show that the step-skewing method can reduce the value of the cogging torque on the permanent magnet synchronous generator. The greater the number of magnetic segments (j), the smaller the cogging torque value.Index Terms—Cogging, Segment, Skewing, PMSG.

Abstract

Milk is a highly nutritious food ingredient because fresh milk contains a variety of complete and balanced food substances such as protein, fat, carbohydrates, minerals, and vitamins. Dairy products that have high nutritional value can easily become a place for the development of microorganisms. Microorganisms that breed in milk can cause changes in the color, aroma, and taste of the milk, eventually spoiling the milk. Pasteurization of milk used in the dairy industry uses the LTST (Low Temperature Long Time) and HTST (High Temperature Short Time) methods. Pasteurization by heating milk can reduce the nutritional content of milk. Pulse Electric Field (PEF) is a non-thermal food processing method that provides electric shocks in the form of high-voltage pulses to foodstuffs for a certain time at room temperature. In this study, the design of an electroporator system for milk pasteurization using PEF was carried out. The results of the pasteurization process using an electroporator are considered to be able to reduce the amount of bacteria contained in milk. The highest field strength produced by this tool is able to touch the figure of 32 kV/cm with a maximum voltage of 48 kV. By setting the pump motor duty cycle of 14% and the pasteurization time of 3 minutes, the milk condition has a longer shelf life than unpasteurized fresh milk. These results are evidenced by the methylene blue reductase test in milk, where 100 ml of milk is homogenized with 1 ml of methylene blue and then waited until the milk turns white.

Abstract

Continuous pasteurization system is a pasteurization system where the material goes to the pasteurization site and is pasteurized in a short time. Continuous pasteurization is widely used in industrial scale. In a continuous pasteurization system, a motor and pump system is needed to move milk from one process to another. One type of motor that can be used as a pump is a separate-excited DC motor. DC motors can provide large torque and are easy to control so that DC motors are often found in various applications such as pumps, conveyors, and others. In this study, a simulation will be carried out using MATLAB/SIMULINK r2017a to determine the characteristics of the separately-excited DC motor when given a change in the duty cycle of the armature voltage to the rotor speed and the armature current when given load torque variation and nominal load torque. It was found that at zero load and nominal load torque, speed of the motor is directly proportional to the increase in the duty cycle of the armature voltage. Meanwhile, when the motor is given a nominal torque load so that it rotates at the nominal speed and then the load is increased until it reaches 5 times th

Abstract

This research is to explain how to use the SEPIC Converter for regeneratif braking using a supercapacitor and its impact on the BLDC motor regeneratif braking process and the supercapacitor charging process. This research was conducted by simulating a BLDC motor regeneratif braking system with a supercapacitor load on the PSIM software. Tests were carried out by varying the duty cycle value of the MOSFET SEPIC converter with a value between 10% to 80% with binding variabels in the form of motor braking time, braking torque, converter input voltage and current, and converter output voltage and current. The results obtained in this study are, the greater the duty cycle value, the faster the braking of the BLDC motor will be. This is indicated by the braking torque which appears to be getting bigger. In addition, the duty cycle value also affects the working system of the converter, where when duty cycle value below 50% making it work as a buck converter or reducing voltage, and if the duty cycle value is below 50% it will make the converter work as a boost converter or voltage booster. Efficiency converters range from 90.8% to99.9% with a maximum efficiency value of 50% duty cycle, and a minimum efficiency value of 80% duty cycle. The duty cycle value also affects the supercapacitor charging process, where the smaller the duty cycle value makes more energy stored in the supercapacitor, due to the greater current flowing.Keywords : BLDC Motor, Regeneratif Braking, SEPIC converter, supercapacitor.

Abstract

The V-shaped blade turbine is one of the turbine models with good self-starting capability, although its efficiency is still standard. Various studies, especially of foil shape and blade swept angle variations applied to V-shaped blade turbines, have been carried out to improve its performance. This study aims to optimize the ability of a V-shaped blade turbine in terms of efficiency and self-starting by investigating the effect of blade aspect ratio and solidity through several test scenarios. NACA 634021 foil and a blade swept angle of 30° were used to create the main form of a V-shaped blade turbine. The simulation results using the QBlade software show that the blade aspect ratio and solidity significantly affect the efficiency and self-starting capability of the V-shaped blade turbine. Finally, the optimal design configuration was achieved on the turbine dimensions with a height of 3.1344 m, a radius of 1.8288 m, a chord foil length of 0.2134 m, and a total of four blades. This configuration can achieve maximum efficiency of 0.441 and fulfills self-starting at the minimum tip speed ratio limit of 0.7.

Abstract

Sistem Wireless Power Transfer (WPT) menggunakan gelombang medan magnet sebagai metode pengiriman daya. Medan magnet pada metode kopling induktif bekerja pada jarak dekat. Parameter sistem WPT perlu ditentukan untuk meningkatkan efisiensi sistem. Rangkaian LC kumparan pengirim dan penerima membutuhkan frekuensi resonansi yang sama untuk pengiriman daya maksimum. Selain itu, konfigurasi bentuk dan jarak antar kumparan juga perlu diperhitungkan untuk menghasilkan fluks yang maksimum. Pada penilitian ini dilakukan simulasi dan penghitungan efisiensi WPT kemudian dilakukan analisis pengaruh variasi frekuensi dan jarak antar kumparan terhadap efisiensi WPT. Hasil simulasi dan penghitungan menunjukan jarak antar kumparan berbanding terbalik dengan efisiensi WPT. Semakin besar frekuensi maka nilai efisiensi semakin besar. Jarak dan frekuensi optimum untuk mencapai efisiensi maksimum pada simulasi adalah 0,001 m dan frekuensi 220 KHz dengan nilai efisiensi 24,888%. Sedangkan pada penghitungan jarak dan frekuensi paling optimum untuk mencapai efisiensi maksimum adalah 0,001 m dan frekuensi 220 KHz dengan efisiensi 18,8855%.

Abstract

DC-DC converters are an important component in modern power systems. This converter is used to convert DC voltage from one level to another, which is indispensable in various types of applications ranging from everyday electronic equipment to industrial use. By using an isolated DC-DC full bridge converter, a transformer is needed as a separator between the input and output parts as well as a voltage booster in the boost converter. However, when the primary current flowing is high, the ferrite core of the transformer is easier to saturate, so in this study the authors designed a transformer modification by dividing the transformer into two (split). In addition to reducing the risk of saturation due to current, with the split transformer, it also reduces the vertical dimensions of the transformer (more flat), so that heat dissipation is also getting better. With the two transformers divided, the two transformers are paralleled on the primary side and serialized on the secondary side, this causes the difference in current ratio in the transformer before and after the split. Before the split, the winding ratio was 3:10 while after the split it became 3:5. From simulations and calculations performed on FEMM and Octave, on the secondary AWG 24, the comparison of the simulated primary current with the AWG maximum current in the maximum winding before the split is 0.47%, while in the transformer after the split is 0.2%, on the secondary AWG 22, before the split is 0.9% and after the split is 0.59%, on the secondary AWG 20, before the split is 1.78% and after the split is 0.7%. For the resulting primary copper loss, it shows that the transformer after the split shows a smaller copper loss. For core loss in one transformer before the split is lower with an average of 15 Watts, while core loss in two transformers after the split is greater with an average of 28 Watts. Keywords: Transformer, split, current ratio, copper loss, core loss.
