style="text-indent:25px">我們俗稱的電源其實是電源轉(zhuǎn)換器。電源轉(zhuǎn)換器根據(jù)轉(zhuǎn)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(jù)轉(zhuǎn)換方式的不同又分為：線性電源和開關電源；根據(jù)調(diào)控效果分類又分為：穩(wěn)壓、恒流、調(diào)頻、調(diào)相。電源模塊作為電子行業(yè)的一種電源轉(zhuǎn)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(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。河北充電電源用途</p></p><br
