style="text-indent:25px">為了完成多個大功率電源模塊的并聯(lián)輸出，目前國內(nèi)的工程師通常會選擇使用外環(huán)均流調(diào)節(jié)模式、內(nèi)環(huán)均流調(diào)節(jié)模式或外置控制器均流調(diào)節(jié)模式，以此完成均流調(diào)節(jié)。其中，外置控制器均流調(diào)節(jié)模式已經(jīng)逐漸成為均流調(diào)節(jié)的主要發(fā)展方向。采用外置控制處理器之后，處理器將會處理來自各模塊和負(fù)載上的電壓和電流取樣信號，并采用某種控制策略，產(chǎn)生各功率單元所需的電壓控制信號Vconi（i=1，2，……，n）從而達(dá)成控制并聯(lián)系統(tǒng)、實現(xiàn)穩(wěn)壓和均流的控制目的。在實際的操作過程中，因為外置控制器和各并聯(lián)模塊需要眾多的信號連接，如果采用模擬方式實現(xiàn)，就需要過多的電纜連接線，系統(tǒng)就極易受到各種干擾，造成穩(wěn)定性和可靠性的降低，而且模擬控制器難以實現(xiàn)優(yōu)化的控制策略。嘉定區(qū)大功率電源模塊多少錢一個</p><p
