德國(guó)力士樂Rexroth放大版VT-VSPA1-52-1X

放大器是能把輸入訊號(hào)的電壓或功率放大的裝置，由電子管或晶體管、電源變壓器和其他電器元件組成。用在通訊、廣播、雷達(dá)、電視、自動(dòng)控制等各種裝置中。
增加信號(hào)幅度或功率的裝置，它是自動(dòng)化技術(shù)工具中處理信號(hào)的重要元件。放大器的放大作用是用輸入信號(hào)控制能源來(lái)實(shí)現(xiàn)的，放大所需功耗由能源提供。對(duì)于線性放大器，輸出就是輸入信號(hào)的復(fù)現(xiàn)和增強(qiáng)。對(duì)于非線性放大器，輸出則與輸入信號(hào)成一定函數(shù)關(guān)系。放大器按所處理信號(hào)物理量分為機(jī)械放大器、機(jī)電
放大器
放大器、電子放大器、液動(dòng)放大器和氣動(dòng)放大器等，其中用得zui廣泛的是電子放大器。隨著射流技術(shù)（見射流元件）的推廣，液動(dòng)或氣動(dòng)放大器的應(yīng)用也逐漸增多。電子放大器又按所用有源器件分為真空管放大器、晶體管放大器、固體放大器和磁放大器，其中又以晶體管放大器應(yīng)用zui廣。在自動(dòng)化儀表中晶體管放大器常用于信號(hào)的電壓放大和電流放大，主要形式有單端放大和推挽放大。此外，還常用于阻抗匹配、隔離、電流-電壓轉(zhuǎn)換、電荷-電壓轉(zhuǎn)換（如電荷放大器）以及利用放大器實(shí)現(xiàn)輸出與輸入之間的一定函數(shù)關(guān)系（如運(yùn)算放大器）。
