style="text-indent:25px">我們俗稱的電源其實是電源轉換器。電源轉換器根據轉換形式可以分成：AC-AC（周波變換器）、AC-DC（整流器）、DC-DC（變換器）、DC-AC（逆變器）4類；根據轉換方式的不同又分為：線性電源和開關電源；根據調控效果分類又分為：穩(wěn)壓、恒流、調頻、調相。電源模塊作為電子行業(yè)的一種電源轉換裝置，它被應用在各種工業(yè)自動化行業(yè)。電源模塊基于開關電源技術，采用好的原材料，結合特殊的模塊化生產工藝制作而成。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很好性，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，應用也越來越常見。崇明區(qū)充電電源生產線充電電源是供蓄電池充電用的整流裝置。</p><div

style="text-indent:25px">充電電源模塊要有故障保護功能，有關統(tǒng)計數據表明，電源模塊在預期有效時間內失效的主要原因是外部故障條件下損壞。而正常使用失效的機率是很低的。因此延長模塊電源壽命、提高系統(tǒng)可靠性的重要一環(huán)是選擇保護功能完善的產品，即在電源模塊外部電路出現故障時電源模塊能夠自動進入保護狀態(tài)而不至于失效，外部故障消失后應能自動恢復正常。電源模塊的保護功能應至少包括輸入過壓、欠壓、軟啟動保護；輸出過壓、過流、短路保護，大功率產品還應有過溫保護等。良好的熱設計可延長電源模塊和其周圍元器件的使用壽命。</p><div
