style="text-indent:25px">源模塊作為電子行業(yè)的一種電源轉(zhuǎn)換裝置，它被廣地應用在各種工業(yè)自動化行業(yè)。電源模塊基于開關(guān)電源技術(shù)，采用質(zhì)量的原材料，結(jié)合特殊的模塊化生產(chǎn)工藝制作而成。它具有模塊化設計、防潮、抗震動、一致性好、應用簡單，可靠性高等優(yōu)點。隨著科學技術(shù)飛速發(fā)展，對電源可靠性、容量、體積的要求越來越高，模塊電源越來越顯示出其優(yōu)越性，憑借它工作頻率高、體積小、可靠性高、便于安裝和擴容的優(yōu)勢，應用也越來越廣。電源模塊多采用高耐壓隔離技術(shù)，隔離耐壓高達2000VAC，充分地保證了設計電路在電壓暫升或暫降時的電路安全穩(wěn)定的運行。就工業(yè)設計應用而言，電源的作用是不容替代的，電源的穩(wěn)定性極大地決定了產(chǎn)品整體的穩(wěn)定，電源的體積重量規(guī)格也極大程度上決定了PCB板的設計，這也是為什么要把質(zhì)量的電源模塊作為電源的原因。江蘇智慧燈桿電-源質(zhì)量商家SLC能夠控制多種不同的燈具:

style="font-size:12px;">推挽式電源電流瞬態(tài)響應速度很高，電壓輸出特性很好，在所有拓撲結(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。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，會使磁芯進入飽和，導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。</span>
