(1)運算電路:將外部的速度、轉(zhuǎn)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(qū)動電路:驅(qū)動主電路器件的電路。它與控制電路隔離使主電路器件導(dǎo)通、關(guān)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(jù)指令和運算可使電動機按指令速度運轉(zhuǎn)。
(5)保護電路:檢測主電路的電壓、電流等,當(dāng)發(fā)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。逆變器
同整流器相反,逆變器是將直流功率變換為所要求頻率的交流功率,以所確定的時間使6個開關(guān)器件導(dǎo)通、關(guān)斷就可以得到3相交流輸出。以電壓型pwm逆變器為例示出開關(guān)時間和電壓波形。逆變器
