碩士 === 國立臺灣科技大學 === 電機工程系 === 102 === This thesis studies the design and implementation of a non-isolated dual-half-bridge bidirectional DC-DC converter. Using the presented topology, high efficiency can be achieved under wide-range load variations by the zero-voltage-switching features and phase-shift control method. In this thesis, dsPIC33FJ16GS502 digital signal controller (DSC) is utilized to implement the digital controller of the bidirectional DC-DC converter. According to the experimental results, a light-load efficiency over 92 % and a full-load efficiency over 97% can be achieved.
