碩士 === 中原大學 === 機械工程研究所 === 100 === Abstract In order to reduce the size of power banks and save cost, this paper proposed a DC-DC converter boost and buck circuit to make the output voltage and current could be controlled in the original default values. And because of the high frequency of designed system, the volume could be smaller, weight could be lighter and efficiency higher. This study for the parts of the DC-DC converter, execute selection and design.And used the PWM to control MOSFET to stably control the output voltage to achieve savings cost and reduce the consumption of power. In order to test and verify the accuracy and feasibility of designed power banks, proposed eight different situation to experiment and research how to compromise output capacitors and output inductorsm to stable output voltage, reduce the size and reduce weight.
