Abstract

This study focused on the development of a buck converter module that will be utilized in the Department of Electrical Engineering laboratory. The design of a buck converter involves the statement of design specifications and calculation of predesign estimates. It also involved the selection and of the circuit's vital components such as the input filter capacitor, output filter capacitor, filter choke, MOSFET, and the controller IC. The controller IC chosen for this device is UC3573, which is optimized for buck converter and a voltage-mode control method with pulse-to-pulse current limiter. The final stage of the design involves the creation of schematic and PBC diagrams. The fabrication stage involves the PCB creation and soldering. The PCB design and the components were integrated into a 4" x 6" PCB. Tests using the fabricated buck converter showed that the measured output voltages were consistent within the input voltage range of 10-15V. The average measured output voltage was 5.022V and it was supported by DC waveform. Tests resulted in low line and load regulations. After the tests confirmed the functionality of the converter, laboratory exercises involving and focusing on the buck converter module were created. The laboratory exercise created include objectives, materials, methods, and some guide questions.
