本研究研製一部直流/直流轉換器，利用同步整流升壓轉換器減少整體系統損耗，並結合交錯式拓樸多相並聯，分散傳輸功率。電路可分為電力級與控制級，電力級由三相升壓轉換器並聯而成，具六顆功率開關元件；控制級則由多組周邊電路與微控制器組成，藉由回授電路偵測電感電流與輸出電壓，於微控制器內部進行追控升壓，達到穩定輸出電壓。本研究可應用於車用充電系統，利用既有的馬達電感，反向做為電池充電升壓轉換器之電感。
系統微控制器使用TI TMS320F280049C做為控制核心，搭配輔助電源、電壓/電流回授電路、開關隔離驅動電路、保護電路以及接觸器電路。控制方面採用雙環控制，具較好的動態響應，提升系統可靠性，且各相皆有獨立的內環，各自分開計算，以解決三相電流分流不均的問題。
本研究主要貢獻為：(1)實作一部三相交錯式升壓轉換器，降低總輸入電流漣波，由400 V輸入升壓至800 V穩定輸出電壓，達到功率7.2 kW；(2)同步整流升壓轉換器三相並聯，減少二極體導通損耗，亦減少單相轉換器電感銅損，系統實測效率97.2%；(3)可應用於電動車車載充電系統基礎研製，節省DC/DC轉換器製造成本與空間，追求系統一體化。

This research develops a DC/DC converter that employs synchronous rectification boost converter to reduce system losses and combines interleaved topology with multiphase parallel operation to distribute power transmission. The circuit can be divided into the power stage and the control stage. The power stage consists of three boost converters in parallel with six power switching devices. The control stage comprises multiple peripheral circuits and a microcontroller, which uses feedback circuits to monitor the inductor current and output voltage and implements control algorithms to maintain a stable output voltage. This research result can be applied to automotive charging systems by utilizing the existing motor inductor, as a boost converter inductor.
Micro-controller, TI TMS320F280049C, is used as the main control unit, with peripheral circuit including auxiliary power, voltage/current feedback circuit, gate driver isolating circuit, protective circuit and contactor circuit. Dual-loop control is implemented to achieve better dynamic response and enhances system reliability. Each phase is equipped with an independent inner control loop, effectively solving the problem of imbalance of current sharing.
The main contributions of this research are: (1) Implement three-phase interleaved boost converter, which can reduce the total input current ripple, with full-load power of 7.2 kW and rated voltage 400 V, boosted to 800 V, (2) Three-phase synchronous rectification boost converter reduces diode conduction losses and inductor copper losses. The system achieves a measured efficiency of 97.2%, (3) The proposed converter has potential applications in vehicle charging systems by utilizing existing motor inductor as boost converter inductor, with the goals of reducing manufacturing costs and space for DC/DC converter.
