碩士 === 國立臺北科技大學 === 電機工程系所 === 101 === With the great advance of technology, the stable and efficient power requirements are highly demanded. The power converters used in parallel can provide the power supply with high reliability and high power output. The paralleled power converters must ensure that the output current of each module is with the same current according to current sharing technology. Therefore, this study intends to use Arduino as a control core to replace multiple analog control IC and implement the current sharing controller by software. The developed multi-module parallel DC-DC digital power converter ensures each power module can evenly share the load current, then improve the efficiency of multi-module power supply. The experimental results show that the error rate of the paralleled current sharing technology in this study can maintain in 5% and the efficiency can achieve 90% or more. In addition, by Bluetooth interface, we use App Inventor based on Arduino environmental development tools to write a remote monitoring program. Then we can make the connection between a mobile device and Arduino via a wireless way. Users can adjust the controller parameters from remote online to save the tuning time of the controller, and monitor the system information by mobile devices from remote area in real time.
