rexroth放大器能把輸入訊號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)控制等各種裝置中原理:高頻功率放大器用于發(fā)射機(jī)的級作用是將高頻已調(diào)波信號進(jìn)行功率放大,以滿足發(fā)送功率的要求,然后經(jīng)過天線將其輻射到空間,保證在一定區(qū)域內(nèi)的接收機(jī)可以接收到滿意的信號電平,并且不干擾相鄰信道的通高頻功率放大器是通信系統(tǒng)中發(fā)送裝置的重要組件。按其工作頻帶的寬窄劃分為窄帶高頻功率放大器和寬帶高頻功率放大器兩種,窄帶高頻功率放大器通常以具有選頻濾波作用的選頻電路作為輸出回路,故又稱為調(diào)諧功率放大器或諧振功率放大器;寬帶高頻功率放大器的輸出電路則是傳輸線變壓器或其他寬帶匹配電路,因此又稱為非調(diào)諧功率放大器。高頻功率放大器是一種能量轉(zhuǎn)換器件,它將電源供給的直流能量轉(zhuǎn)換成為高頻交流輸出在 “低頻電子線路”課程中已知,放大器可以按照電流導(dǎo)通角的不同,將其分為甲、乙、丙三類工作狀態(tài)。
力士樂比例閥放大板對控制過程中反映出來的微弱信號進(jìn)行放大(電流或電壓)以驅(qū)動(dòng)比例閥參數(shù)按比例隨之變化,實(shí)現(xiàn)自動(dòng)控制的目的。比例放大板主要是通過電流的大小改變驅(qū)動(dòng)壓力大小。是使用精度高點(diǎn),而且是電流控制的比例閥;這樣放大板的功能才能發(fā)揮的。比例閥需要的電壓通常是24伏,工作電流在200-800毫安之間。這么大的電流,PLC和計(jì)算機(jī)的D/A數(shù)據(jù)卡都無法達(dá)到這么高,直流只有20-30毫安左右,電壓在0-10伏,所以要加一個(gè)放大器,才能推動(dòng)比例閥。
