部分組成。主電路采用單端反激式拓撲，它是升降壓斬波電路演變后加隔離變壓器構成的，該電路具有結構簡單，效率高，輸入電壓范圍寬等優(yōu)點?？刂齐娐肥钦麄€開關電源的中心，控制的好壞直接決定了電源整體性能。這個電路采用峰值電流型雙環(huán)控制，即在電壓閉環(huán)控制系統(tǒng)中加入峰值電流反饋控制。這類方案選擇合適的變壓器及MOS管可以把功率做的很大，與前面幾種設計方案相比電路結構復雜，元器件參數(shù)確定比較困難，開發(fā)成本較高，因此需要此方案時可以優(yōu)先選擇市面上比較廉價的DC/DC隔離模塊。</p><p style="text-indent:25px">DC-DC直流電源和交流電源比較大的區(qū)別是什么：交流電源是現(xiàn)代詞，是一個專有名詞，指的是插頭與插座指用來接上用來將市電提供的交流電，使家用電器與可攜式小型設備通電可使用的裝置。家用交流電源插頭與插座指用來接上用來將市電提供的交流電，使家用電器與可攜式小型設備通電可使用的裝置。電源插頭有棒狀或銅板狀突出的公接頭，以物理方式插入有插槽或凹洞的母接頭型的電源插座。插頭上一般都有火線(孔洞較短)、中性線接頭(孔洞較長)，部分還有接地接頭(**圓孔)。有多種插頭并未特別區(qū)分火線與中性線，而也有些接頭會有多個火線。這些接頭可能鍍上了銅、錫、鎳電源插座是有插槽或凹洞的母接頭，用來讓有棒狀或銅板狀突出的電源插頭插入，以將電力經插頭傳導到電器。一般插座都設計成非同一規(guī)格的插頭就無法插入，部分插座上會有棒狀突出，搭配插頭上的凹洞。DC-DC直流電源單相整流電路，要求達到“簡單應用”層次。</p><div

style="text-indent:25px">DC-DC直流電源技術指標：DC-DC直流電源的技術指標：一種是特性指標，包括允許輸入電壓、輸出電壓、輸出電流及輸出電壓調節(jié)范圍等；另一種是質量指標，用來衡量輸出直流電壓的穩(wěn)定程度，包括穩(wěn)壓系數(shù)（或電壓調整率）、輸出電阻（或電流調整率）、紋波電壓（周圍與隨機漂移）。穩(wěn)壓系數(shù)及電壓調整率：穩(wěn)壓系數(shù)是指在負載電流、環(huán)境溫度不變的情況下，輸入電壓的相對變化引起輸出電壓的相對變化。電壓調整率是指輸入電壓相對變化為±10%時的輸出電壓相對變化量，穩(wěn)壓系數(shù)和電壓調整率均說明輸入電壓變化對輸出電壓的影響，因此只需測試其中之一即可。DC-DC直流電源經整流濾波后直流電壓由R1提供給調整管的基極。濟南小功率DC-DC直流電源</p><p style="text-indent:25px">DC-DC直流電源工具應絕緣良好。防止在查找和處理過程中造成新的接地。濟南小功率DC-DC直流電源</p><p style="text-indent:25px">DC-DC直流電源技術指標：1.輸出電阻及電流調整率：輸出電阻與放大器的輸出電阻相同，其值為當輸入電壓不變時，輸出電壓變化量與輸出電流變化量之比的一定值。電流調整率：輸出電流從0變到zui大值時所產生的輸出電壓相對變化值。輸出電阻和電流調整率均說明負載電流變化對輸出電壓的影響，因此也只需測試其中之一即可。2.紋波電壓：疊加在輸出電壓上的交流電壓分量。用示波器觀測其峰峰值一般為毫伏量級。也可用交流毫伏表測量其有效值，但因紋波不是正弦波，所以有一定的誤差。一般只能用于所需電流強度較小的電路。為了取得較大的電流強度，可以將等電動勢的DC-DC直流電源并聯(lián)使用，這時總電動勢即為單個電源的電動勢，總內阻為各電源內電阻的并聯(lián)值。濟南小功率DC-DC直流電源</p><p
