The boost converter is an application of a switching device that increases the breakdown voltage. The reason for doing it is that design engineers always encounter problems of not having enough voltage to form their design to function effectively. By adding an extra voltage supply to a circuit was never the best choice, especially relating to cost-saving. The DC-to-DC converter is known to have high efficiency, low supply voltage, and small in size. Therefore, using a Boost Converter's power is a solution where it can be obtained from any suitable DC sources, such as DC generators, rectifiers, solar panels, and batteries while maintaining low cost. Hence, this work is about to relate the breakdown voltage with a Boost Converter. It was simulated in LTspice software, which is a robust simulation language specifically optimized for Switch Mode Power conversion. Varying the inductor's value is done to observe and analyze the inductor ripple current and output voltage in this paper. The simulation from LTspice successfully shows that the input voltage, 12 V boosts up to 28 V of the output voltage at the lowest inductor value 470 μH. While as the inductor value increased, the ripple current decreased significantly.
