按输入电压等级分类变频器按输入电压等级可分低压变频器和高压变频器，低压变频器国内常见的有单相220 V变频器、三相220 V变频器、i相380 V变频器。高压变频器常见有6 kV、10 kV变压器，控制方式一般是按高低一高变频器或高一高变频器方式进行变换的。 2．按变换频率的方法分类变频器按频率变换的方法分为交-交型变频器和交-直交型变频器。交-交型变频器可将工频交流电直接转换成频率、电压均可以控制的交流，故称直接式变频器。交直-交型变频器则是先把工频交流电通过整流装置转变成直流电，然后再把直流电变换成频率、电压均可以调节的交流电，故又称为间接型变频器。 3．按直流电源的性质分类在交-直-交型变频器中，按主电路电源变换成直流电源的过程中，直流电源的性质分为电压型变频器和电流型变频器
