Abstract

The application of high voltage becomes more important and wider. High voltage is needed in the process of reducing air contaminants, waste treatment, sanitation, disinfecting microorganisms, testing for insulating high voltage equipment, and transmitting electrical energy. The problem of high voltage AC generation system is still in a large scale, static, not portable, and very expensive. This paper presents an analytical design of a high-voltage AC high-frequency based on power electronic. It is portable, less expensive, and eaasier to control the amplitudo and frequency. The application of the Full Bridge Bipolar Inverter topology with the Sinusoidal Pulse Width Modulation switching method provides variable sinusoidal AC voltage outputs (Vo) on its amplitude and frequency. The Tesla Coil Transformer amplifies the amplitude in accordance with the classification of the high voltage AC in the order of Kilo Volt. The Closed Loop control system in the Bipolar Inverter Full Bridge topology provides high accuracy results between the given setting values and the actual amplitude output and the expected high-frequency AC voltage. Analysis of the SPWM switching pattern parameter settings shows stability for several loading variations

Abstract

DC-DC converter are required in industrial application to convert a fixed DC voltage into a variable DC voltage. This article focuses on the cuk converter topology which can operate in buck-boost mode which is regulated through the duty cycle pulse width modulation setting and controlled by the dsPIC33EP512MU810 microcontroller by applying the Proportional-Integral (PI) digital closed loop current control method. Using PI control method is considered capable of producing optimal performance and increasing the response time that occurs. The frequency given by the generator signal is used as a reference signal to inject current into the inductor (L1). The current sensor module acts as a measuring device and a reader of the actual current value that appears through the load. The difference between the reference current value and the actual value will produce an error signal value so that it becomes the comparison value of the current sensor results with the PI control method. Simulation results on PSIM, modeling analysis, device implementation and hardware testing graphs in the laboratory have been carried out to prove the design parameters and proposed methods can work as intended.

Abstract

Abstract-- Renewable drive technology is developing in the current era, one of which is electric transportation. The Switched Reluctance Motor (SRM) was chosen for the transportation development because it has many advantages, including not using permanent magnets and simple construction in the form of an iron core in the rotor and stator windings. SRM works based on the reluctance phenomenon, namely, if the stator is energized, the stator will attract the nearby rotor, this is based on the tendency of the rotor poles to align with the stator excitation poles. SRM requires high speed switching control to operate and requires correct rotor position to operate. Maximum switching and good accuracy can use Field-Programmable Gate Array (FPGA) and rotary encoder as input for rotor position information. To use SRM in electric transport, it is necessary to adjust the speed with ease and precision. With the Pulse Width Modulation (PWM) technique, the size of the excitation depends on the size of the current, the size of the current is determined by the input voltage to the SRM. In this control, the PWM width can be changed by setting the carrier set and modulation set in the FPGA program. In this study, it is proposed to control the SRM speed by adjusting the PWM of the rotary encoder to produce the desired RPM. To support the achievement of this research, hardware testing was carried out in the laboratory.Keywords-- Duty cycle, FPGA, PWM, Reluctance, Switched Reluctance Motor.

Abstract

The development of electrical energy sources has been the primary focus in recent decades, driven by the increasing global demand for electricity. This phenomenon marks a global shift towards more sustainable and environmentally friendly energy sources. One key aspect of this development is related to various technologies in power generation, including synchronous generators. Synchronous generators play a crucial role in the electrical energy infrastructure due to their ability to produce power stably and efficiently, meeting the demand for reliable and high-quality electricity supply. In the context of the role of synchronous generators, it is important to understand how these generators react to variable capacitive loading. This capacitive loading can affect the overall efficiency and performance of the power generation system. In this situation, the influence of capacitive loading is particularly evident in the formation of reactive power. The reactive power generated can significantly affect the speed and frequency of synchronous generators. Furthermore, the effects of capacitive loading can also be felt in the voltage of the system. Voltage fluctuations may occur, often requiring compensation in the form of field current to maintain system stability. Therefore, a deep understanding of how synchronous generators respond to capacitive loading is crucial to ensuring optimal performance of the power generation system as a whole, as well as in formulating strategies to improve the efficiency and reliability of electrical energy in the future.              Keywords: Capacitive, Excitation System, Resistive, Synchronous Generator. ABSTRAKPerkembangan sumber energi listrik telah menjadi fokus utama dalam beberapa dekade terakhir seiring dengan meningkatnya kebutuhan akan energi listrik di seluruh dunia. Fenomena ini menandai pergeseran global menuju sumber energi yang lebih berkelanjutan dan ramah lingkungan. Salah satu aspek utama dari perkembangan ini adalah terkait dengan berbagai teknologi dalam pembangkit listrik, di antaranya adalah generator sinkron. Generator sinkron memiliki peran penting dalam infrastruktur energi listrik karena kemampuannya untuk menghasilkan daya secara stabil dan efisien, memenuhi tuntutan masyarakat akan pasokan listrik yang andal dan berkualitas. Dalam konteks peran generator sinkron, penting untuk memahami bagaimana generator tersebut bereaksi terhadap pembebanan kapasitif yang variatif. Pembebanan kapasitif ini dapat memengaruhi efisiensi dan kinerja keseluruhan dari sistem pembangkit listrik. Dalam situasi ini, pengaruh dari pembebanan kapasitif terutama terlihat dalam pembentukan daya reaktif. Daya reaktif yang dihasilkan dapat mempengaruhi putaran dan frekuensi generator sinkron secara signifikan. Selain itu, efek dari pembebanan kapasitif juga dapat dirasakan pada tegangan dalam sistem. Fluktuasi tegangan dapat terjadi, yang sering kali memerlukan kompensasi dalam bentuk arus medan agar stabilitas sistem tetap terjaga. Oleh karena itu, pemahaman yang mendalam tentang bagaimana generator sinkron dengan pembebanan kapasitif menjadi sangat penting dalam memastikan kinerja yang optimal dari sistem pembangkit listrik secara keseluruhan, serta dalam merumuskan strategi untuk meningkatkan efisiensi dan keandalan energi listrik di masa depan.
