、直流電源的工作原理

　 IUXPOWER系列高頻開(kāi)關(guān)直流電源采用了全橋移相式脈寬調(diào)制軟開(kāi)關(guān)控制技術(shù)，使得模塊效率進(jìn)一步提高，諧波減小。高頻開(kāi)關(guān)直流電源模塊采用三相三線380VAC平衡輸入，無(wú)相序要求，無(wú)中線電流損耗，在交流輸入端，采用先進(jìn)的尖峰抑制器件及EMI濾波電路。高頻開(kāi)關(guān)直流電源由全橋整流電路將三相交流電整流為直流，經(jīng)無(wú)源功率因數(shù)校正（PFC）后，再由DC/DC高頻變換電路把所得的直流電逆變成穩(wěn)定可控的直流電輸出。

　　高頻開(kāi)關(guān)直流電源脈寬調(diào)制電路（PWM）及軟開(kāi)關(guān)諧振回路根據(jù)電網(wǎng)和負(fù)載的變化，自動(dòng)調(diào)節(jié)高頻開(kāi)關(guān)的脈沖寬度和移相角，使輸出電壓電流在任何允許的情況下都能保持穩(wěn)定。YK郵科系列電力高頻開(kāi)關(guān)電源既可單機(jī)工作完成各種基本功能，又可并聯(lián)組合工作，并具有良好的并機(jī)均流效果。高頻開(kāi)關(guān)直流電源通過(guò)與微機(jī)連接，可實(shí)現(xiàn)"遙測(cè)、遙信、遙控、遙調(diào)"四遙功能。高頻開(kāi)關(guān)直流電源具備完善的保護(hù)功能，保證模塊或模塊組獨(dú)立運(yùn)行和微機(jī)監(jiān)控下系統(tǒng)的安全、穩(wěn)定。高頻開(kāi)關(guān)直流電源模塊采用總線采樣主、從均流控制方式。在并機(jī)運(yùn)行時(shí)，高頻開(kāi)關(guān)直流電源模塊組中能自動(dòng)選出一臺(tái)主模塊，將分流器采集到的電流、電壓等外部參數(shù)進(jìn)行處理，集中控制每一臺(tái)模塊的輸出電壓、電流。從而，即使在小電流時(shí)，也能得到較好的均流效果。

　　當(dāng)市電經(jīng)過(guò)輸入開(kāi)關(guān)接通變壓器將市電電壓轉(zhuǎn)換成所設(shè)計(jì)的電壓后,進(jìn)入了預(yù)穩(wěn)壓電路,預(yù)穩(wěn)壓電路是對(duì)所要的輸出電壓進(jìn)行初步穩(wěn)壓,其目的是降低大功率調(diào)整管的輸入與輸出之間的管壓降，減少大功率調(diào)整管的功耗，提高直流電源的工作效率，預(yù)穩(wěn)壓電源一般由可控硅無(wú)級(jí)移相調(diào)整式用繼電器切換變壓器輸出的抽頭進(jìn)行穩(wěn)壓。經(jīng)過(guò)預(yù)穩(wěn)壓電源和濾波器后，得到的電壓基本穩(wěn)定紋波相對(duì)較小的直流電源，經(jīng)過(guò)在控制電路的控制的大功率調(diào)整管進(jìn)行精確快速的問(wèn)頂壓后，將得到穩(wěn)壓精度和性能符合標(biāo)準(zhǔn)的直流電壓再經(jīng)過(guò)濾波器；進(jìn)行濾波后既得到我的所需要的輸出直流電為了得到我的所需要的輸出電壓值或穩(wěn)流電流值，我們還需要對(duì)輸出的電壓值和電流值進(jìn)行取樣檢測(cè)并將其傳送到控制/保護(hù)電路，控制/保護(hù)電路將檢測(cè)到的輸出電壓值錢和電流值與電壓/電流設(shè)定電路所設(shè)定的值進(jìn)行比較分析后驅(qū)動(dòng)預(yù)穩(wěn)壓電路和大功率調(diào)整管使直流穩(wěn)壓電源能輸出我們所設(shè)定的電壓和電流值，同時(shí)當(dāng)控制/保護(hù)電路檢測(cè)到異常的電壓或電流值等情況下將啟動(dòng)保護(hù)電路使直流電源進(jìn)入保護(hù)狀態(tài)。
