ABB變頻器ACS310-03E-41A8-4功率18.5KW

變頻器組成

主電路

主電路是給異步電動機提供調壓調頻電源的電力變換部分，變頻器的主電路大體上可分為兩類：電壓型是將電壓源的直流變換為交流的變頻器，直流回路的濾波是電容。電流型是將電流源的直流變換為交流的變頻器，其直流回路濾波是電感。它由三部分構成，將工頻電源變換為直流功率的“整流器”，吸收在變流器和逆變器產生的電壓脈動的“平波回路”，以及將直流功率變換為交流功率的“逆變器“。

整流器

大量使用的是二極管的變流器，它把工頻電源變換為直流電源。也可用兩組晶體管變流器構成可逆變流器，由於其功率方向可逆，可以進行再生運轉。

平波回路

在整流器整流後的直流電壓中，含有電源6倍頻率的脈動電壓，此外逆變器產生的脈動電流也使直流電壓變動。為了抑制電壓波動，採用電感和電容吸收脈動電壓（電流）。裝置容量小時，如果電源和主電路構成器件有餘量，可以省去電感採用簡單的平波回路。

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個開關器件導通、關斷就可以得到3相交流輸出。以電壓型pwm逆變器為例示出開關時間和電壓波形。 [4]

控制電路是給異步電動機供電（電壓、頻率可調）的主電路提供控制信號的回路，它有頻率、電壓的“運算電路”，主電路的“電壓、電流檢測電路”，電動機的“速度檢測電路”，將運算電路的控制信號進行放大的“驅動電路”，以及逆變器和電動機的“保護電路”組成。

（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。
