電源模塊的拓撲結構有多種，反激、正激、推挽、半橋、全橋多種，每種因為其原理的不同，也表現(xiàn)為在某些特性指標方面的優(yōu)越性。反激電源在開關的一個周期中，充電的時段沒有放電，就是因為這個特性，其時間響應特性、紋波特性就很難做到很好，雖然可以通過大的儲能電容協(xié)助解決一點，但原理性缺點終歸是硬傷，智力不足是可以通過勤勞來彌補，但補來補去遇到臨界難題的時候終歸跨不過某個坎兒。漏感也大等等問題，但其優(yōu)點是電路簡單，成本低，體積小，不必加磁復位繞組，而且輸入電壓范圍比較寬。也正因為此，才有了其占總電源市場7成以上的份額。正激電源輸出電壓瞬態(tài)控制特性較好，負載能力較強，但其缺點也同樣，多用一個大儲能濾波電感和一個續(xù)流二極管、體積大、變壓器初級線圈反電動勢電壓高，對開關管的要求較高（容易擊穿損壞）。 </p><p style="text-indent:25px">高頻機與工頻機比較而言：尺寸小、重量輕、運行效率高（運行成本低）、噪音低，適合于辦公場所，性價比高（同等功率下，價格低），對空間、環(huán)境影響小，相對而言，高頻充電機對復印機、激光打印機和電動機引起的沖擊（SPIKE）和暫態(tài)響應（TRANSIENT）易受影響，由于工頻機的變壓器把市電與負載隔離，對市電惡劣的環(huán)境下，工頻機比高頻機能提供更安全和可靠的保護，在某些場合如醫(yī)療等，要求充電機有隔離裝置，因此，對工業(yè)、醫(yī)療、交通等應用，工頻機是較好的選擇。兩者的選擇要根據(jù)客戶的不同、安裝環(huán)境、負載情況等條件權衡考慮。智慧燈桿電源是一款智能電源。</p><div

style="text-indent:25px">所有電子產(chǎn)品都有壽命，電源也不例外。如果使用壽命已經(jīng)到了，卻沒有即時更換，只會造成更大的損失。智能型電源的工作時間顯示分為單次工作時間以及累計工作時間。當超過使用壽命時，顯示會閃爍提醒我們必須及早更換，避免損失。智能型電源不但具備上述功能，還可以直接安裝在導軌上。與導軌安裝的其他裝備形成一體，使用方便、美觀并且安規(guī)谻證齊全。更可以選用備源使用功能，強化電源異常時的急救時間，不用因維修而停機。歡迎來電咨詢天磁科技。智能電源具備良好的性能與溫度控制技術。北京電-源方案</p><p style="text-indent:25px">可通過RS485、以太網(wǎng)等遠程實現(xiàn)電源通斷。深圳智能燈桿電-源方案</p><p style="text-indent:25px">輸出電壓過低：針對電源模塊輸出參數(shù)異常——輸出電壓過低。這可能會導致整體系統(tǒng)不能正常工作,如微控制器系統(tǒng)中,負載突然增大,會拉低微控制器供電電壓,容易造成復位。并且電源長時間工作在低輸入電壓情況下,電路的壽命也會出現(xiàn)極大的折損。因此輸出電壓偏低的問題是不容忽視的,那么輸出電壓過低通常是那些原因造成的呢?輸入電壓較低或功率不足;輸出線路過長或過細,造成線損過大;輸入端的防反接二極管壓降過大;輸入濾波電感過大。針對這一類問題,可以通過調(diào)整供電或者更換相應的外圍電路來改善,具體如下所示:調(diào)高電壓或換用更大功率輸入電源;調(diào)整布線,增大導線截面積或縮短導線長度,減小內(nèi)阻;換用導通壓降小的二極管;減小濾波電感值或降低電感的內(nèi)阻。深圳智能燈桿電-源方案</p></p><br
