InterphaseDVX-2601真空发生器
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
