Abstract

The monitoring system used in electric cars is a vehicle condition display where the vehicle has a main drive in the form of a BLDC hub motor and a PSMS type controller. The aim of this research is to measure the temperature of the controller using a temperature sensor (DS18b20), measure battery voltage using a series of resistors, current sensor using ACS712. The input used is the sensor input which is used to detect a condition or physical change which is required in the system output. Arduino Uno R3 hardware is used to receive, manage and provide electrical signals. A user interface or user interface device is needed so that the operation of the system can be known. In this experiment, a Nextion LCD was used as a user interface. The reading tests that have been carried out produce quite varied responses, but are still within normal limits. This shows that the tests carried out have been successfully carried out well. As a result, the tool created can display data accurately, with the display data being displayed at all times as long as the power supply receives power input. The ADEV 01 Monalisa electric car vehicle condition monitoring system prototype was designed and made with smart technology which can later be developed properly and can be used to produce good and precise displays. By experimenting with the vehicle in a stationary condition, the average difference produced in the battery voltage data shows a difference of 0.284 V, in the current data using the instrument it shows a difference of 0.622 mA, in the controller temperature data it shows a difference of 1.24 ℃, with the experiment in the condition of the vehicle in speed conditions low, the average difference produced in the battery voltage data shows a difference of 0.245 V, in the current data for the instrument it shows a difference of 0.183 mA, in the controller temperature data it shows a difference of 0.074 ℃, with experimental conditions of the vehicle in high speed conditions the average difference produced in The battery voltage data shows a difference of 0.083 V, the instrument current data shows a difference of 0.79 mA, the controller temperature data shows a difference of 1.192 ℃.

Abstract

Light, as an electromagnetic phenomenon, can be elucidated as both a wave and a particle. The wave-particle duality portrays light as an electromagnetic wave and discrete particles known as photons. The spectrum of light represents the wavelength in a visual array of colors. Optics, a vital field in physics, delves into the characteristics of light. Light, an electromagnetic wave with a wavelength of 380-750 nm, exhibits dual nature as both a wave and a particle. Light intensity is measured in lumens or lux, indicating the strength of a light source in a specific direction per unit angle. The human eye, sensitive to the visible light spectrum, holds significance in optics and photometry. Light sensors such as LDR, Photodiode, and BH1750 sensor transform light information into electronic signals for electronic devices like the Arduino Uno microcontroller. The research was methods by measuring light intensity for 5 days at 3 different times (morning, noon and afternoon) simultaneously and open area. The parameters that form the basis of the comparison include error values, stability in the calibration process, light intensity measurement range, and sensor price. Data was collected at the same time during the day to ensure consistent test conditions. Based on the research findings, the BH1750 sensor was selected as the most effective among the three sensors used, exhibiting the smallest average error value of 0.755%. It is easily calibrated, has a wide intensity measurement range (0-65535 lux), and comes at a relatively affordable price.

Abstract

Energy needs have always been a problem that must be solved, the utilization of fossil energy sources is a solution that is widely used, but this energy source can run out at any time. The idea to create an energy producer that utilizes mechanical energy from the motion of objects, creating a tool in the form of a floor that can produce electrical energy by utilizing piezoelectricity as a harvester with SSHI technique as an optimizer. Piezoelectric is a sensor that can react when given vibration or pressure. The energy harvesting floor is made using piezoelectrics arranged in series of 16 pieces, this harvesting tool is assisted by standard energy harvesting (SEH) and syncronized swiych harvesting inductor (SSHI) techniques this technique combines several components namely, MOSFET IRF530N, Inductor, reactifier, capacitor. This floor can produce 5V AC energy in a few steps, and produce 2V - 2.5V DC after entering the rectifier, after being given a load in the form of a capacitor and LED the voltage generated per beat is 0.03V - 0.06V, this study compares the harvesting circuit using SSHI and not using SSHI, getting the conclusion SSHI as a harvesting stabilizer dampens the resulting power surge.

Abstract

When an induction motor starts up, it draws a large current, which can damage it and cause a voltage dip effect that interferes with other electrical equipment. The machine, however, has numerous applications, particularly in the industrial sector, due to its low cost, robustness, and dependability. Induction motor performance must be improved to reduce starting current surges and protect against overcurrent. Thyristors are used in the developed system to control the voltage level. The microcontroller's trigger pulse causes a ramp-up in supply voltage, resulting in a soft-starting effect in a 1-phase induction motor. The system detects overcurrent using the popular current sensor module. This research results in a high-performing soft starter and overcurrent detector. When compared to supplying the motor directly online, the soft-starter unit can reduce the starting current by 55%. Meanwhile, the embedded overcurrent detector performs admirably, accurately detecting motor overcurrent and cutting off the power supply when the motor reaches overcurrent.

Abstract

The design of a pure sine wave inverter based on the EGS003 aims to improve the efficiency of electrical energy conversion. This inverter development method integrates PWM (Pulse Width Modulation) control with a pure sine wave reference signal. The use of PWM control allows precise adjustment of the pulse width of the output signal, according to the desired sine wave characteristics. Consequently, this inverter is capable of producing pure sine waves without significant harmonic distortion, enhancing the quality of the generated power and reducing energy losses due to harmonic distortion. This research involves the implementation of EGS003 technology, which is a dedicated PWM controller designed for inverter applications. The use of this controller enables the optimization of resource utilization and enhances energy conversion efficiency. Furthermore, the development of the EGS003-based inverter involves the analysis and design of control circuits in line with modern power electronics principles. This includes adjusting PWM control parameters to various load characteristics, allowing the inverter to operate optimally under different usage conditions. The design results demonstrate that the pure sine wave inverter based on EGS003 provides satisfactory performance in delivering output compliant with power quality standards. With the capability to generate pure sine waves without significant harmonic distortion, this inverter has broad application potential in power systems requiring high-quality power. Additionally, the use of PWM control technology in this inverter facilitates ease of operation adjustment and monitoring, enhancing the overall reliability and efficiency of the system.
