做為三相交流/交流轉換器之矩陣型轉換器具有高效率、高可靠度及低成本之特色。其包含以下優點，可操作於四個象限中、控制輸入側至單位功因、於虛擬直流鏈不需一電容做為緩衝而可進行交流/交流直接轉換，於輸入側及輸出側皆可有優良表現並無低頻之諧波，而其缺點為其控制法則較為複雜及其低調變比。
矩陣型轉換器中又可分為直接式和間接式，本論文將以間接式之架構作為研究方向，其組成和直接式相同皆僅以功率開關組成。而間接式矩陣型轉換器之架構可視為整流側及逆變側之組合，整流側主要為選擇市電側之兩相並將其線對線電壓作為一虛擬直流鏈，而逆變側與一般二階式轉換器相似，故其可使用脈波寬度調變(Pulse Width Modulation, PWM)法做調變將虛擬直流鏈組合成期望之輸出電壓。
本論文將介紹以全載波調變之間接式矩陣型轉換器之換相法則以及其補償方式、基於電流合成之時序計算並操作於過調變區域，實驗平台以德州儀器之數位訊號處理器(Digital Signal Process, DSP) TMS320F28335作為中央處理器，進行電壓命令的計算及區間判斷，再將命令送到場域可程式化邏輯閘陣列(Field Programmable Gate Array, FPGA)以判斷出開關訊號、製作出死區時間及實現補償機制。

The matrix converter as a three-phase AC/AC converter has the characteristics of high efficiency, high reliability and low cost. It includes the following advantages, It can be operated in four quadrants, control the input side to unit power factor and can directly process AC/AC conversion do not need a capacitor as a buffer in the virtual DC link. Both on the input side and the output side has excellent performance and no low-frequency harmonics, but its disadvantage is that its control rule is more complicated and its low linear duty ratio.
The matrix converter can be divided into direct and indirect. This thesis will take the indirect structure as the research direction. Its power stage structure same as the direct matrix converter only consists of power switches. The structure of the indirect matrix converter can be seen as a combination of the rectifier side and the inverter side. The rectifier side mainly selects the two phases of the grid side and uses its line-to-line voltage as a virtual DC link. The inverter side is similar to a conventional two-level converter, so it can use the Pulse Width Modulation (PWM) method to modulate the virtual DC link into the desired output voltage.
This thesis will introduce the commutation rule and compensation method of the full-carrier modulation indirect matrix converter, the timing calculation based on current synthesis and operate in the over-modulation area. The experimental testbench use the digital signal processor (DSP)of Texas Instruments TMS320F28335 as a central processor to execute voltage command calculation and mode judgment, then send the command to the Field Programmable Gate Array (FPGA) to determine the switching signal and implementation deadtime and compensation mechanism.
