VVVF变频、矢量控制变频、直接转矩控制变频都是交—直—交变频中的一种。其共同缺点是输入功率因数低，谐波电流大，直流电路需要大的储能电容，再生能量又不能反馈回电网，即不能进行四象限运行。为此，矩阵式交—交变频应运而生。由于矩阵式交—交变频省去了中间直流环节，从而省去了体积大、价格贵的电解电容。它能实现功率因数为l，输入电流为正弦且能四象限运行，系统的功率密度大。该技术虽尚未成熟，但仍吸引着众多的学者深入研究。其实质不是间接的控制电流、磁链等量，而是把转矩直接作为被控制量来实现的

变频器容量选定过程，实际上是一个变频器与电机的最佳匹配过程，最常见、也较安全的是使变频器的容量大于或等于电机的额定功率，但实际匹配中要考虑电机的实际功率与额定功率相差多少，通常都是设备所选能力偏大，而实际需要的能力小，因此按电机的实际功率选择变频器是合理的，避免选用的变频器过大，使投资增大。对于轻负载类，变频器电流一般应按1.1N（N为电动机额定电流）来选择，或按厂家在产品中标明的与变频器的输出功率额定值相配套的最大电机功率来选择
