Correction”意思是“功率因數(shù)校正”。功率因數(shù)指的是電源對電網(wǎng)供給的電能的利用效率。功率因數(shù)越高表示其對電網(wǎng)電能的利用率越高。功率因數(shù)的高低跟咱們自家電費無關，只是提升電網(wǎng)供電的利用率。PFC目前有主動式PFC，被動式PFC和交錯試PFC。 </p> <p> 被動式PFC： </p> <p> 低端電源常用，特點是PFC電感**固定在電源殼上。 </p> <p> **電源常用的交錯試PFC。通常挨著大電容。 </p> <p> 跟一般主動式PFC一個不同的是，一般的主動式PFC是一個電感。交錯試的是兩個相同相鄰的電感而已。 </p><p> 對于很多人來說，對于電源適配器的概念只停留在充電器的階段，但實際上電源適配器是一種變壓器，被大量應用在充電器上。對于電源適配器不熟悉的人往往需要面對的，是采用哪種電源適配器來進行充電 </p> <p> 電源適配器的參數(shù)多種多樣，因此并不能隨意使用適配器來進行充電。在選擇電源適配器之前，首先要確定三個適配條件 </p> <p> ①適配器的接口與設備匹配 </p> <p> ②輸出電壓必須與負載的額定輸入電壓相同，或者在負載)可承受的電壓范圍，否則，可能燒毀負載 </p> <p> ③電源適配器的輸出電流應等于、大于負載的電流，以提供足夠的電力 </p> <p> 下面就來對上述的三條適配條件進行分析 </p> <p> ①不匹配的接口在沒有專業(yè)知識的情況下千萬不要亂插，否則會發(fā)生危險 </p> <p> ②對于為什么需要電壓一致，從原理上講是這樣的——電壓不足，不足以驅(qū)動負載，電池無法正常充電 </p> <p> ③對于為什么需要這樣的電流配置，這要涉及到電路的原理，大家都知道電源是有內(nèi)阻的，內(nèi)阻越大損耗越大。因此廠家在生產(chǎn)這個適配器的時候就會根據(jù)內(nèi)阻大小，確定空載輸出電壓在一定范圍內(nèi)，而電壓臨界值對應的電流臨界值即為我們看到的電流標稱值，電流標稱值越大說明適配器帶載能力越好。所以選擇電流略大的適配器不但不會傷害電池，反而會讓充電變得更快新賽電源適配器所有原材料均經(jīng)過嚴格的質(zhì)量認證，保證產(chǎn)品的質(zhì)量及安全。</p><div

在現(xiàn)代社會，電子設備早已經(jīng)和人們的生活如影隨形。作為眾多電器產(chǎn)品的標準配置，也被人們所熟悉。由于我國人口眾多，居住密度也緊湊，所以我國的家用電是220V的交流電。這比起一些其他國家的家用電要高的多，于是在使用電子設備我們通常都要使用電源適配器。 </p> <p> 電源適配器對電子產(chǎn)品的用電安全有著重大影響，不單單決定了電子產(chǎn)品的安全系數(shù)，同時也是電子設備用電安全的一把安全鎖。但不得不承認的是，國內(nèi)很多電源適配器的檢測不合格現(xiàn)象仍舊很多，無法通過質(zhì)檢的產(chǎn)品不在少數(shù)。 </p> <p> 前幾天，江蘇的徐先生電動車在充電的時候很容易就把燈泡燒壞，本來以為是電路的問題，誰知叫電工一查，原來是徐先生購買的劣質(zhì)電源適配器的原因。劣質(zhì)或“三無”的充電器在充電過程中極易產(chǎn)生強大脈沖波，對內(nèi)部變壓器產(chǎn)生逆變，相當于加了一只小型逆變器，因此，導致電壓升高燒壞了燈泡。 </p> <p>

U=0。U=E，以下內(nèi)容分別介紹這三種狀態(tài)的具體情況。 </p> <p> 通路狀態(tài)： </p> <p> <br /> </p> <p> 通路就是電路中的開關閉合，負載中有電流流過。在這種狀態(tài)下，電源適配器端電壓與負載電流的關系可以用電源適配器外特性確定，根據(jù)負載的大小，又分為滿載、輕載、過載三種情況。負載在額定功率下的工作狀態(tài)叫額定工作狀態(tài)或滿載;低于額定功率的工作狀態(tài)叫輕載;高于額定功率的工作狀態(tài)叫過載。由于過載很容晚燒壞電器，所以一般情況都不允許出現(xiàn)過載。廣東國標電源適配器多少錢</p><p
