實(shí)現(xiàn)優(yōu)質(zhì)高效的電力線載波通信的關(guān)鍵在于所選用的載波調(diào)制解調(diào)模塊和相應(yīng)的接口電路。電力線接口電路將調(diào)制解調(diào)部分和電力線耦合，實(shí)現(xiàn)信號(hào)在電力線上的傳輸。通信過程要求這個(gè)接口電路在發(fā)送信號(hào)時(shí)，對(duì)信號(hào)進(jìn)行濾波處理，濾除一定的噪聲如二次諧波，并通過功率放大器使信號(hào)有足夠的功率耦合到電力線上；在接收時(shí)，對(duì)混雜在信號(hào)中的噪聲進(jìn)行濾除，并放大信號(hào)，然后將信號(hào)傳送到調(diào)制解調(diào)模塊中進(jìn)行解調(diào)。因此接口電路的性能決定了通信效果的好壞。一般地，電力線接口電路包括：接收部分、發(fā)送部分、功率放大部分和保護(hù)部分等。因?yàn)镾T7538內(nèi)部帶有功率放大電路，所以只需設(shè)計(jì)接收、發(fā)送和保護(hù)三個(gè)部分。電力線接口電路如圖3所示。
發(fā)送電路部分，電容C11、電感LC12、電感L4和等效感性阻抗LC的值一般是事先給定的，需要通過計(jì)算確定的是電容C13和CR9的值。在選定C11、LC12、L4和LC的值時(shí)要注意變壓器的漏電感、晶體二極管的電容和串聯(lián)器件（C13、LC12、T1、L4、C11）的等效串聯(lián)電阻ESR（100mΩ～1Ω） ，所以盡可能地選用電阻性器件。變壓器選用1:1的隔離變壓器。模擬電力線的阻抗條件，即給濾波器的輸出端加上一個(gè)感性負(fù)載，令其阻抗特性為2LC = 100μH。電路中的感性器件的ESR要與其電感值成比例，且感性器件的ESR要盡可能地小。電感選用LBC（大線軸帶繞磁心），電感值盡可能小，所以 LC12的值選為10μH，L4的值選為22μH。C11的作用是將變壓器與電力線隔離，過濾電力線上的50/60Hz的信號(hào)，阻止低頻信號(hào)進(jìn)入電路而使某些高頻信號(hào)通過，選取X2型電容，這種電容具有短路保護(hù)功能，所以C11的值一般選為33nF/400V。根據(jù)極點(diǎn)頻率公式，計(jì)算得出C13的值為 220nF，CR9的值為100nF。
