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。具体方法是：[8]控制定子磁链引入定子磁链观测器，实现无速度传感器方式；[8]自动识别(ID)依靠的电机数学模型，对电机参数自动识别；[8]算出实际值对应定子阻抗、互感、磁饱和因素、惯量等算出实际的转矩、定子磁链、转子速度进行实时控制；

此外回路损耗也使谐振过电压受到阻尼和限制。当回路电阻大于一定的数值时，就不会出现强烈的铁磁谐振过电压。3）串联谐振电路来说，产生铁磁谐振过电压的的必要条件是ω0=1/L0C<；因此铁磁谐振可在很大的范围内发生。4）维持谐振振荡和抵偿回路电阻损耗的能量均由工频电源供给。为使工频能量转化为其它谐振频率的能量，其转化过程必须是周期性且有节律的，即…1/2(1，3…）倍频率的谐振。5）铁磁谐振对PT的损坏。电磁谐振（分频）一般应具备如下三个条件。①铁磁式电压互感器（PT）的非线性效应是产生铁磁谐振的主要原因。②PT感抗为容抗的100倍以内，即参数匹配在谐振范围。③要有激发条件，如PT突然合闸、单相接地突然消失、外界对系统的干扰或系统操作产生的过电压等。
