The project entails the design and implementation of a boost converter along with a self-designed DC power supply. The objective is to create a boost converter that takes an input from the DC power supply, which has a regulated output voltage of 9 volts, and produces a fixed output voltage of 12 volts. The boost converter should have a maximum power rating of 0.4W and minimize variation in the output voltage.

To begin, a risk analysis is conducted to identify potential risks that may arise during the circuit's implementation and operation. Strategies to mitigate these risks are developed to ensure safe and effective execution of the project.

Theoretical analysis is performed to derive the necessary equations and formulas based on fundamental theory. This analysis aids in understanding the principles underlying the design of the boost converter and enables the selection of appropriate components such as transformers, rectifiers, and PID controllers.

Simulation studies are conducted using software such as Proteus to validate the design and evaluate its performance. These simulations provide valuable insights into the behavior of the circuit, allowing for adjustments and optimizations as necessary.

Following successful simulations, the circuit design is implemented in hardware. Care is taken to adhere to the design criteria, but any deviations are validated with proper justifications. Safety guidelines are strictly followed throughout the hardware implementation, including precautions for overcurrent and overvoltage risks, careful handling of components, and the presence of at least two individuals during circuit energization.

Throughout the project, emphasis is placed on the importance of safety when working with high voltages. Proper personal protective equipment (PPE) is worn, and safety protocols are followed diligently to minimize any potential hazards.
