逆变器

同整流器相反，逆变器是将直流功率变换为所要求频率的交流功率，以所确定的时间使6个开关器件导通、关断就可以得到3相交流输出。以电压型pwm逆变器为例示出开关时间和电压波形。 

控制电路是给异步电动机供电（电压、频率可调）的主电路提供控制信号的回路，它有频率、电压的“运算电路”，主电路的“电压、电流检测电路”，电动机的“速度检测电路”，将运算电路的控制信号进行放大的“驱动电路”，以及逆变器和电动机的“保护电路”组成。

（1）运算电路：将外部的速度、转矩等指令同检测电路的电流、电压信号进行比较运算，决定逆变器的输出电压、频率。 

（2）电压、电流检测电路：与主回路电位隔离检测电压、电流等。 

（3）驱动电路：驱动主电路器件的电路。它与控制电路隔离使主电路器件导通、关断。 [

（4）速度检测电路:以装在异步电动机轴机上的速度检测器(tg、plg等)的信号为速度信号，送入运算回路，根据指令和运算可使电动机按指令速度运转。

（5）保护电路：检测主电路的电压、电流等，当发生过载或过电压等异常时，为了防止逆变器和异步电动机损坏。
