Voltage regulators are crucial components in power supply modules that maintain a stable output voltage despite a variation in input voltage or changes in load current. It will prevent damage or malfunction caused by voltage spikes or drops and is widely used in various applications to ensure the reliability and safe operation of an electronic system. The final year project report illustrates the knowledge and experiences gained. Next, voltage regulators are designed and implemented as part of the learning process. Furthermore, it involves the simulation of software, troubleshooting, and fabricating PCBs. The two types of voltage regulators are primarily linear and switching voltage regulators. This project studies linear voltage regulators, including Zener Shunts, Transistor Shunts, Transistor Series, Fixed Voltage Regulators, and Variable Voltage Regulators. In addition, these three converter types are commonly analyzed and utilized for switching voltage regulators, namely the Buck converter (step-down converter), Boost converter (step-up converter), and Buck-Boost converter (inverting converter). Software such as NI MultiSIM and LTspiceXVII is used to simulate and design circuits. Next, prototypes are implemented and simulated on breadboards and PCBs. Subsequently, the results of the tests are documented in the report. Finally, an analysis and comparison of simulation results between the breadboard and PCB will be conducted.
