Abstract

DC-DC converters are widely used in regulated switch mode DC power supplies. The input of these converters is an unregulated DC voltage and therefore it will fluctuate due to the disturbances in the system. The output voltage regulation in DC-DC converter is achieved by constantly adjusting the amount of energy absorbed from the source and that injected into the load, which is in turn controlled by the relative durations of the absorption and injection intervals. The objectives of this project are to design a DC-DC boost converter and to make the hardware implementation of the circuit. This system utilized basic open-loop and closed-loop control configurations of the boost converter. The parameter of component values for hardware design can be obtained through some calculation from the theoretical formulae and analysis on MATLAB Simulink software. The methodology of designing the hardware circuit is presented in details. All the simulation results will be verified by the hardware design. The process involved are simulating the boost converter circuit, designing the circuit layout, making the printed circuit board (PCB), testing the PCB board, analysing the data on hardware and drawing conclusion. Hardware implementations have been done in order to verify the operation of the boost converter. From this project, the output voltage obtained in hardware is slightly different compared to the simulation due to some unresolved issues. Other than that, the acceptable results are valid for PWM and gate driver. The efficiency of the boost converter is almost to 1 which is close to the ideal when tested with load variation.
