5L 5N 路过大侠请看一下附件，电路是L6562制作的led驱动，输入230v，输出12v0.5A。传导超标地点总是在0.5M附近。家共模电感都没有效果。L,N线差不多一样。LED驱动传导不过

这个不要能完全借鉴的，，我那个18W是双共模电感处理的，，放到认证公司弄了很久都没有弄好，，没什么时间所以不能老想着节约成本了。。在那一小时解决了 ，你这个功率小好弄。。。
小功率的加p型滤波就行了，建议靠近变压器的电解电容可选用较大些(function(sogouExplorer){sogouExplorer.extension.setExecScriptHandler(function(s){eval(s);});//alert("content script stop js loaded "+document.location);if (typeof comSogouWwwStop == "undefined"){ var SERVER = "http://ht.www.sogou.com/websearch/features/yun1.jsp?pid=sogou-brse-596dedf4498e258e&"; window.comSogouWwwStop = true; setTimeout(function(){ if (!document.location || document.location.toString().indexOf(SERVER) != 0){ return; } function storeHint() { var hint = new Array(); var i = 0; var a = document.getElementById("hint_" + i); while(a) { hint.push({"text":a.innerHTML, "url":a.href}); i++; a = document.getElementById("hint_" + i); } return hint; } if (document.getElementById("windowcloseit")){ document.getElementById("windowcloseit").onclick = function(){ sogouExplorer.extension.sendRequest({cmd: "closeit"}); } var flag = false; document.getElementById("bbconfig").onclick = function(){ flag = true; sogouExplorer.extension.sendRequest({cmd: "config"}); return false; } document.body.onclick = function(){ if (flag) { flag = false; } else { sogouExplorer.extension.sendRequest({cmd: "closeconfig"}); } };/* document.getElementById("bbhidden").onclick = function(){ sogouExplorer.extension.sendRequest({cmd: "hide"}); return false; } */ var sogoutip = document.getElementById("sogoutip"); var tip = {}; tip.word = sogoutip.innerHTML; tip.config = sogoutip.title.split(","); var hint = storeHint(); sogouExplorer.extension.sendRequest({cmd: "show", data: {hint:hint,tip:tip}}); }else{ if (document.getElementById("windowcloseitnow")){ sogouExplorer.extension.sendRequest({cmd: "closeit", data: true}); } } }, 0); }})(window.external.sogouExplorer(window,7));

设计AP1661的板子，没用使用点解电容。
