基準(zhǔn)電壓進(jìn)行比較，產(chǎn)生誤差電壓，從而控制脈沖寬度；③腳為電流檢測輸入端，當(dāng)檢測電壓超過1V時縮小脈沖寬度使電源處于間歇工作狀態(tài)；④腳為定時端，內(nèi)部振蕩器的工作頻率由外接的阻容時間常數(shù)決定，f=1.8/（RT×CT）；⑤腳為公共地端；⑥腳為推挽輸出端，內(nèi)部為圖騰柱式，上升、下降時間*為50ns

style="text-indent:25px">搞懂DC/DC電源怎么回事：DC/DC電源電路又稱為DC/DC轉(zhuǎn)換電路，其主要功能就是進(jìn)行輸入輸出電壓轉(zhuǎn)換。一般我們把輸入電源電壓在72V以內(nèi)的電壓變換過程稱為DC/DC轉(zhuǎn)換。常見的電源主要分為車載與通訊系列和通用工業(yè)與消費系列，前者的使用的電壓一般為48V、36V、24V等，后者使用的電源電壓一般在24V以下。不同應(yīng)用領(lǐng)域規(guī)律不同，如PC中常用的是12V、5V、3.3V，模擬電路電源常用5V 15V，數(shù)字電路常用3.3V等，現(xiàn)在的FPGA、DSP還用2V以下的電壓，諸如1.8V、1.5V、1.2V等。在通信系統(tǒng)中也稱二次電源，它是由一次電源或直流電池組提供一個直流輸入電壓，經(jīng)DC/DC變換以后在輸出端獲一個或幾個直流電壓。南京DC-DC直流電源廠家推薦DC-DC直流電源大部分的電源模塊沒有均流功能，不能直接并聯(lián)使用達(dá)到增大輸出功率的效果。</p><div

style="text-indent:25px">DC-DC直流電源輸入濾波電容器的選擇：鋁電解電容器的額定電壓的1.3倍作為電容器的浪涌電壓，工作電壓高于160V時，是額定工作電壓+50V作為浪涌電壓，這是生產(chǎn)廠家保證的電壓，可以允許在短時間內(nèi)承受此電壓。電容器處于浪涌電壓時，電流會很大，如果時間太長，會爆開。所以鋁電容器應(yīng)該選用額定電壓稍高的，實際工作電壓為標(biāo)稱額定電壓的70~80%為宜，所以選用額定電壓值為400V的鋁電解電容。由于模塊電源體積的限制，在85～265Vac的輸入范圍內(nèi)，前級儲能鋁電解電容的容值一般選取2倍于輸出功率的值，即2.5*2=5，綜上，鋁電解電容的取值以4.7μF/400V為宜。</p><p style="text-indent:25px">DC-DC直流電源供電回路分為環(huán)形供電方式和輻射供電方式。環(huán)形供電網(wǎng)絡(luò)干線或小母線的二回DC-DC直流電源應(yīng)分別經(jīng)直流斷路器接人兩段直流母線，正常時為開環(huán)運行。環(huán)形供電網(wǎng)絡(luò)干線引接負(fù)荷支路應(yīng)設(shè)置直流斷路器。DC-DC直流電源系統(tǒng)支路直流熔斷器和直流斷路器級差配合原則:應(yīng)注意上下級之間的配合。當(dāng)直流斷路器與熔斷器配合時，應(yīng)考慮動作特性的不同，對級差做適當(dāng)調(diào)整。直流斷路器下一級不宜再接熔斷器。上、下級均為直流斷路器的，額定電流宜按照4級及以上電流級差選擇配合。蓄電池出口為熔斷器，下級為直流斷路器的，宜按照2倍及以上額定電流選擇級差配合。變電站內(nèi)設(shè)置直流保護(hù)電器的級數(shù)不宜超過4級。DC-DC直流電源輸出電阻及電流調(diào)整率：輸出電阻與放大器的輸出電阻相同。</p><div
