style="text-indent:25px">電源就是把其他形式的能量轉(zhuǎn)化成電能的裝置。即：電源是提供電能的裝置。因?yàn)樗梢詫⑵渌问降哪苻D(zhuǎn)換成電能，所以我們把這種提供電能的裝置叫做電源。從定義中我們可以看出平時我們理解的“電源”不都屬于電源，比如我們經(jīng)常用到的手機(jī)充電器，它是把220V的交流市電轉(zhuǎn)換成5V直流電，可以說只是改變了電能的一種形式，我們可以稱它為電源轉(zhuǎn)換裝置。那電源轉(zhuǎn)換裝置又是如何定義的呢？能夠?qū)㈦娏δ茉吹男问竭M(jìn)行控制、轉(zhuǎn)換的裝置。因此，我們俗稱的電源其實(shí)是電源轉(zhuǎn)換器。電源轉(zhuǎn)換器根據(jù)轉(zhuǎn)換形式可以分成：AC-AC（周波變換器）、AC-DC（整流器）、DC-DC（變換器）、DC-AC（逆變器）4類；根據(jù)轉(zhuǎn)換方式的不同又分為：線性電源和開關(guān)電源；根據(jù)調(diào)控效果分類又分為：穩(wěn)壓、恒流、調(diào)頻、調(diào)相。深圳燈桿電-源方案基于OneNET協(xié)議兼容特性，實(shí)現(xiàn)不同廠家的設(shè)備協(xié)議兼容和互通。</p><div

走線阻抗大。電源模塊輸出與負(fù)載連接必然要有一段PCB走線，走線越長、走線越窄則它的等效電阻越大。等效電阻可以認(rèn)為是串聯(lián)在負(fù)載的工作回路中，將起到分壓作用，因此導(dǎo)致負(fù)載兩端的電壓小于模塊的輸出電壓。此外，除了走線問題還有很多情況起到類似的作用，比如焊點(diǎn)接觸不良導(dǎo)致等效電阻增加，線路氧化或腐蝕導(dǎo)致等效電阻增加。<span style="font-size:12px;">防反接二極管。很多產(chǎn)品的AC和DC部分是不在一塊板上的，在生產(chǎn)或終端客戶使用中不可避免涉及到插拔電源連接器的情況。為防止此過程中的反接導(dǎo)致的硬件損壞，常串入一只二極管解決。以壓降0.7V的二極管為例，b1 b2間的電壓將比a1 a2間電壓小0.7V，這也就是上面所討論的輸入電壓偏低的情況，可以通過選擇壓降低的管子或者直接提高a1 a1間電壓的方法解決。</span> </p> <p> </p><p style="text-indent:25px">特種電源即特殊種類的電源。所謂特殊主要是由于衡量電源的技術(shù)指標(biāo)要求不同于常用的電源，其主要是輸出電壓特別高，輸出電流特別大，或者對穩(wěn)定度、動態(tài)響應(yīng)及紋波要求特別高，或者要求電源輸出的電壓或電流是脈沖或其它一些要求。這就使得在設(shè)計(jì)及生產(chǎn)此類電源時有比普通電源有更特殊甚至更嚴(yán)格的要求。特種電源一般是為特殊負(fù)載或場合要求而設(shè)計(jì)的，它的應(yīng)用十分***。主要有：電鍍電解、陽極氧化、感應(yīng)加熱、醫(yī)療設(shè)備、電力操作、電力試驗(yàn)、環(huán)保除塵、空氣凈化、食品滅菌、激光紅外、光電顯示等。而在**及***上，特種電源更有普通電源不可取代的用途，主要用于：雷達(dá)導(dǎo)航、高能物理、等離子體物理及核技術(shù)研究等。智慧電源可分別對每路進(jìn)行電壓、電流、及電路采集。</p><div

電源指示燈不亮，充電指示燈也不亮。檢查充電器輸入電源插頭與市電有沒有連接好，可將充電器輸入插頭插至正常的電源插座中試一下，如情況依舊，將充電器外殼打開，觀察一下機(jī)內(nèi)保險(xiǎn)絲有沒有斷，如沒有斷，先檢查一下電源輸入線是否良好，在排除電源輸入線的故障后，應(yīng)檢查一下電路板上高壓區(qū)附近的元器件是否有虛焊，保險(xiǎn)絲座是否有接觸不良現(xiàn)象，重點(diǎn)檢查變壓器T1、三極管V1、V2等是否有虛焊現(xiàn)象。另外，R5或R6開路，也會引起上述故障，如機(jī)內(nèi)保險(xiǎn)絲已斷，則千萬不要更換大安培的保險(xiǎn)絲管（充電器的保險(xiǎn)絲管一般為2A），應(yīng)重點(diǎn)檢查D1-D4、V1、V2、R4、R7及D15、D21有無損壞，如有損壞，可用同類型的更換。請注意，上述元件損壞時，可能會同時損壞一到二個，有時可能會同時損壞好幾個，檢修時需要逐一檢查、更換這些元件后才能通電。支持5路輸出，并具有PWM調(diào)光輸出（DALI可選）。北京智能燈桿電-源</p><p

推挽式電源電流瞬態(tài)響應(yīng)速度很高，電壓輸出特性很好，在所有拓?fù)浣Y(jié)構(gòu)中，是利用率比較高的一種開關(guān)電源，無漏磁，驅(qū)動電路簡單。但其缺點(diǎn)是兩個開關(guān)器件需要很高的耐壓值；要有兩組初級線圈，對于小功率輸出的推挽式開關(guān)電源是個缺點(diǎn)。若兩個正激式變換器不完全對稱或平衡，經(jīng)過幾個周期累積的偏磁，會使磁芯進(jìn)入飽和，導(dǎo)致高頻變壓器勵磁電流過大，甚至損壞開關(guān)管。橋式開關(guān)電源輸出功率很大，工作效率很高，開關(guān)管的耐壓值要求比較低，變壓器初級線圈只需要一個繞組。缺點(diǎn)是效率低，會出現(xiàn)半導(dǎo)通區(qū)，損耗大。以上各種問題都是因?yàn)槠渫負(fù)浣Y(jié)構(gòu)的先天優(yōu)勢和先天缺點(diǎn)造成的，雖然我們可以將電源模塊當(dāng)成黑匣子，但這也是我們在選擇電源時要關(guān)注的一個點(diǎn)。因?yàn)槟芡瓿赏瑯庸δ艿脑O(shè)計(jì)方案，一個很輕松地完成，一個要費(fèi)很大的勁才能完成。浙江智慧路燈電-源品牌好嗎</p></p><br
