“…The researcher focuses on the flyback-topologybased LED Driver component, essential for converting PLN electrical energy from alternating current (AC) to direct current (DC) to satisfy LED lamp requirements. The function of converting from AC to DC must be accompanied by the efficiency and stability of electrical energy output to improve lamp efficiency and maintain voltage and current output stability so that the lamp can last longer [19]. The load specifications will be used as a reference for designing the LED driver.…”

<span lang="EN-US">This research aims to design a flyback topology switch-mode power supply constant voltage and constant current light emitting diode (LED) driver to improve the performance of the LED. The flyback topology is chosen for its simple design and small size and uses high-frequency switching to lower the high DC voltage from the power source. The research aims to avoid blackouts caused by a drop in the power source voltage and to produce technological products that can be developed for other lighting applications. The constant-voltage feedback system ensures that the current flowing to the LED remains stable despite changes in load or other conditions. When there is a voltage drop from the power source, this topology can maintain the voltage and current stable and in accordance with the working voltage specifications of the LEDs. According to test results, the LED driver's output voltage ranges from 18.03 to 18.06 volts with an average message error value of 0.3%. In this system, switching occurs at frequencies ranging from 18.041 Hz to 38.230 Hz. With a constant current value of 0.58 ampere, the resulting lamp's lux value is stable and does not significantly change.</span>

Developing and analyzing a versatile Thermoelectric Cooler and Heater (TEC/H) device, aiming to investigate its working principles, temperature control capabilities, and cooling/heating performance across various input voltage levels. The TEC device is driven by direct current (DC) voltages ranging from 1 V to 5 V, supplied by a DC regulator power source, and controlled using Adreno programming through the Adreno platform. The study employed commonly available components, including a breadboard, USB cable, jumper wires, and Arduino IDE's open serial monitor for data collection and monitoring. The primary objectives of this study are twofold: first, to comprehensively understand the thermoelectric principles governing the TEC/H system's operation, and second, to experimentally assess the device's ability to regulate temperature and provide both cooling and heating functions. The TEC/H system's versatility and adaptability make it a promising candidate for a wide range of applications, including electronic component cooling, environmental temperature control, and thermal management in various domains. This research may contribute to enhancing the understanding of thermoelectric technology and facilitate its implementation in practical applications, ultimately improving energy efficiency and thermal management in various fields.
