 （1）運算電路：將外部的速度、轉矩等指令同檢測電路的電流、電壓信號進行比較運算，決定逆變器的輸出電壓、頻率。
（2）電壓、電流檢測電路：與主回路電位隔離檢測電壓、電流等。
（3）驅動電路：驅動主電路器件的電路。它與控制電路隔離使主電路器件導通、關斷。
（4）速度檢測電路:以裝在異步電動機軸機上的速度檢測器(tg、plg等)的信號為速度信號，送入運算回路，根據指令和運算可使電動機按指令速度運轉。
（5）保護電路：檢測主電路的電壓、電流等，當發生過載或過電壓等異常時，為了防止逆變器和異步電動機損壞，使逆變器停止工作或抑制電壓、電流值。（1）運算電路：將外部的速度、轉矩等指令同檢測電路的電流、電壓信號進行比較運算，決定逆變器的輸出電壓、頻率。
