方案描(miao)述：智(zhi)能家居(ju)控(kong)(kong)制(zhi)(zhi)器最求美觀化，小(xiao)型化，因此(ci)需要控(kong)(kong)制(zhi)(zhi)器的電(dian)路(lu)板在這樣小(xiao)體積是要求下可靠的工作，且要實現智(zhi)能家居(ju)基本的便利(li)功(gong)能：如窗簾控(kong)(kong)制(zhi)(zhi)器應具備有遠(yuan)程控(kong)(kong)制(zhi)(zhi)、面板顯示、場景控(kong)(kong)制(zhi)(zhi)等功(gong)能。

供(gong)電方式：市電(dian)(dian)(dian)(dian)通過(guo)防護電(dian)(dian)(dian)(dian)路(lu)進去到AC-DC電(dian)(dian)(dian)(dian)源模(mo)塊，由電(dian)(dian)(dian)(dian)源模(mo)塊輸(shu)出(chu)穩定的(de)(de)5V電(dian)(dian)(dian)(dian)壓給(gei)后端的(de)(de)處(chu)理(li)器、繼電(dian)(dian)(dian)(dian)器等負載供電(dian)(dian)(dian)(dian)。

方案(an)特點：開關電(dian)源(yuan)的(de)方(fang)案替代變(bian)壓器(qi)(qi)的(de)方(fang)案，通(tong)過(guo)開關電(dian)源(yuan)本身參數的(de)設計(ji)，實(shi)現(xian)(xian)穩(wen)壓輸(shu)出，且附帶過(guo)流(liu)、短路等保護(hu)功能，從而實(shi)現(xian)(xian)外圍電(dian)路簡單(dan)，布板設計(ji)簡潔的(de)特(te)點。由(you)于開關電(dian)源(yuan)采(cai)用高頻控制的(de)方(fang)式(shi)，內部變(bian)壓器(qi)(qi)可以設計(ji)得(de)很小，使得(de)整個開關電(dian)源(yuan)小型化，最(zui)終彌補了上述兩(liang)種方(fang)法的(de)缺點。
