style="text-indent:25px">DC-DC電源模塊有多種封裝形式，不僅滿足國際標(biāo)準(zhǔn)的要求，而且符合國內(nèi)要求，需要在一般原則下進(jìn)行篩選。通常在選擇電源模塊封裝時(shí)，需要做以下三個(gè)方面的工作。在一定的功率條件下，必須確保體積越小越好。在封裝過程中，體積縮小意味著空間的擴(kuò)大，以便為系統(tǒng)的其他部分提供更多的空間，并確保功能的完整性。在封裝選擇上，我們應(yīng)該盡量選擇符合國際標(biāo)準(zhǔn)的產(chǎn)品。因?yàn)閲H標(biāo)準(zhǔn)是針對(duì)全球制造商和要求的，所以要求很高，兼容性性能比較好。此外，世界上有很多采用這一標(biāo)準(zhǔn)的制造商，在選擇供應(yīng)方面有更廣闊的選擇空間，這不會(huì)造成選擇的局限性。在選擇封裝時(shí)，應(yīng)注重可擴(kuò)展產(chǎn)品，以便于今后系統(tǒng)的擴(kuò)展和升級(jí)。在滿足國際要求的基礎(chǔ)上，目前工業(yè)上普遍采用的包裝方式是半磚和全磚包裝。這兩種包裝方式完全可以與國際**品牌Vicor、Lambda等兼容。一般來說，國際上半磚產(chǎn)品的功率覆蓋范圍為50 W/200 W，而全磚產(chǎn)品的功率覆蓋范圍為100 W/300 W，可以滿足國內(nèi)和大多數(shù)國際產(chǎn)品的要求。在DC-DC變換器功率模塊封裝選擇過程中，只要能遵循國際標(biāo)準(zhǔn)和擴(kuò)展性要求的兩個(gè)前提，一般都很容易找到適合產(chǎn)品的封裝形式。</p><p

電源供應(yīng)系統(tǒng)或使用點(diǎn)電源供應(yīng)系統(tǒng)(PUPS)。由于模塊式結(jié)構(gòu)的優(yōu)點(diǎn)甚多，因此模塊電源普遍用于交換設(shè)備、接入設(shè)備、移動(dòng)通訊、微波通訊以及光傳輸、路由器等通信領(lǐng)域和汽車電子、航空航天等。高速發(fā)展的計(jì)算機(jī)技術(shù)帶領(lǐng)人類進(jìn)入了信息社會(huì),同時(shí)也促進(jìn)了電源模塊技術(shù)的迅速發(fā)展。計(jì)算機(jī)多方面采用了開關(guān)電源,率先完成計(jì)算機(jī)電源換代。電路工作象限又可分為一象限、二象限、三象限、四象限。</p><div
