Abstract

Inverter is an electronic circuit that convert electric voltage with direct current (DC) to alternating current (AC). One of the commonly used inverter configuration is H-Bridge circuit. Inverter with H-Bridge circuit does not need voltage-balanced diode or capacitor to operate and can be cascaded to obtain multilevel output voltage. H-Bridge circuit works by adjusting the combination of switches that were enabled. One of the commonly used switches is Metal Oxide Semiconductor Field Effect Transistor (MOSFET). The advantages of MOSFET as switching components are its fast switching speed and it did not cause current tail. Therefore, the writing of this paper aims to design a 12V DC to 220V AC 50Hz single-phase inverter with H-Bridge MOSFET circuit. The design stage begins with determining the specifications of the inverter, creating a block diagram of the inverter, determining the required components, and calculating the required parameters of the inverter. The designed inverter is simulated using Proteus 8.4 software. Simulation results are in accordance with the desired specification.

Abstract

Abstrak Penelitian ini menyajikan perancangan dan analisis sebuah sensor arus yang terdiri dari rangkaian penyearah gelombang penuh dengan filter kapasitor, pembagi tegangan, buffer, dan penguat diferensial. Metode yang digunakan untuk mengukur nilai arus pada sensor adalah dengan menetapkan salah satu resistor pada rangkaian pembagi tegangan sebagai resistor referensi (Rs). Metode ini didasarkan pada hukum Ohm dalam menentukan nilai arus yang melalui suatu jalur. Hasil percobaan yang dilakukan telah membuktikan teori yang disajikan.   Kata Kunci: metode resistif, pengukuran arus, rangkaian sensor arus.

Abstract

The application of magnetic levitation that is currently developing is on land transportation in the form of maglev trains.Magnetic levitation is a system that uses an electromagnetic field to work against the force of gravity. The common point in application the magnetic levitation is used is the lack of contact and thus no friction this increases efficiency and system life. Magnetic levitation technology is still developing today. The magnetic levitation ball requires a good control method to maintain the ball's position on the mat against the earth's surface. This research implements Hybrid Proportional Integral Derivative (PID) control with fuzzy as a control system on magnetic levitation ball. The research for magnetic levitation ball uses Auto Tuning PID and Fuzzy–Takagi Sugeno controls. In the PID system, an auto-tuning system is carried out on simulink MATLAB R2019, and in fuzzy the function is designed to store input in the form of error (e) and delta error (de) while the function displays output in the form of effective height distance. Then defuzzification on fuzzy uses the Center of Area (COA) method. In magnetic levitation research, objects can experience ideal service conditions at a distance of 0.006 m from the end of the solenoid. in the transfer function test to reach a steady state, the risetime is 0.007817 s, the overshoot is 157.051%. then the PID tuning test to reach a steady state obtained a risetime of 0.214371 s, an overshoot of 0.460%. and in the fuzzy-PID hybrid test to reach steady state, the risetime is 0.044902 s and the overshoot is -0.357%.
