VVVF變頻、矢量控制變頻、直接轉矩控制變頻都是交—直—交變頻中的一種。其共同缺點是輸入功率因數低，諧波電流大，直流電路需要大的儲能電容，再生能量又不能反饋回電網，即不能進行四象限運行。為此，矩陣式交—交變頻應運而生。由于矩陣式交—交變頻省去了中間直流環節，從而省去了體積大、價格貴的電解電容。它能實現功率因數為l，輸入電流為正弦且能四象限運行，系統的功率密度大。該技術雖尚未成熟，但仍吸引著眾多的學者深入研究。其實質不是間接的控制電流、磁鏈等量，而是把轉矩直接作為被控制量來實現的

變頻器容量選定過程，實際上是一個變頻器與電機的最佳匹配過程，最常見、也較安全的是使變頻器的容量大于或等于電機的額定功率，但實際匹配中要考慮電機的實際功率與額定功率相差多少，通常都是設備所選能力偏大，而實際需要的能力小，因此按電機的實際功率選擇變頻器是合理的，避免選用的變頻器過大，使投資增大。對于輕負載類，變頻器電流一般應按1.1N（N為電動機額定電流）來選擇，或按廠家在產品中標明的與變頻器的輸出功率額定值相配套的最大電機功率來選擇
