本論文主要在研製輸出功率6 kW、輸入交流電壓220 V、輸出直流電壓800 V之三相功率因數修正器，可應用於微電網系統與電動車充電站等。架構使用Vienna整流器以達成元件數少、架構簡單以及開關耐壓要求低等目的。本文採用一種注入零序訊號的載波脈寬調變做為其控制方式，相比於同樣得到大量使用之空間向量脈寬調變方式，其有調變波形生成容易、不需判斷空間向量區間的特性，同時依然保留空間向量調變方式電壓利用率高之優點。本文先以PSIM模擬軟體建構電路雛型，驗證其數位控制方式之可行性。在實作電路上，選擇德州儀器之TMS320F28335微控制器，以數位控制的方式實現載波脈寬調變。並且選用SiC碳化矽功率元件作為電路架構中之功率開關，實作一部具同步整流功能之高功率三相Vienna整流器。

This thesis aims to study and design a three-phase rectifier with 6 kW output power, 220 V input AC voltage and 800 V output voltage, which could be used on microgrid system and EV charging station. The rectifier applied Vienna topology to achieve the goal of few components, easy structure and low voltage stress on MOSFET. This thesis uses a variant of Carrier-Based PWM as the control scheme. Compare to Space Vector PWM, the modulation waveform of Carrier-Based PWM is easy to produce and there is no need to determine the location of the space vector, but still got the profit of high voltage utilization. This thesis uses simulation software PSIM to construct a prototype of the circuit in order to verify the feasibility of the digital control scheme. In practice, choosing the TMS320F28335 microcontroller from Texas Instrument to achieve Carrier-Based PWM with digital control, choosing SiC component as power MOSFET and making a high power three-phase Vienna rectifier with synchronous rectification.
