降低結(jié)溫等措施以減少器件的應(yīng)力，使得產(chǎn)品的可靠性大大提高。模塊化是開關(guān)電源發(fā)展的總體趨勢(shì)，可以采用模塊化電源組成分布式電源系統(tǒng)，可以設(shè)計(jì)成N+1冗余電源系統(tǒng)，并實(shí)現(xiàn)并聯(lián)方式的容量擴(kuò)展。針對(duì)開關(guān)電源運(yùn)行噪聲大這一缺點(diǎn)，若單獨(dú)追求高頻化其噪聲也必將隨著增大，而采用部分諧振轉(zhuǎn)換電路技術(shù)，在理論上即可實(shí)現(xiàn)高頻化又可降低噪聲，但部分諧振轉(zhuǎn)換技術(shù)的實(shí)際應(yīng)用仍存在著技術(shù)問題，故仍需在這一領(lǐng)域開展大量的工作，以使得該項(xiàng)技術(shù)得以實(shí)用化。電力電子技術(shù)的不斷創(chuàng)新，使開關(guān)電源產(chǎn)業(yè)有著廣闊的發(fā)展前景。要加快我國(guó)開關(guān)電源產(chǎn)業(yè)的發(fā)展速度，就必須走技術(shù)創(chuàng)新之路，走出有特色的產(chǎn)學(xué)研聯(lián)合發(fā)展之路，為我國(guó)國(guó)民經(jīng)濟(jì)的高速發(fā)展做出貢獻(xiàn)。

由于MAX810L的復(fù)位門檻電平為4.65V，因此其RESET端輸出為高電平，迫使Q1關(guān)斷，從而使負(fù)載與輸入電源斷開。MAX668通過外部反饋電阻網(wǎng)絡(luò)設(shè)定5V輸出電壓。當(dāng)輸出電壓超MAX810L的復(fù)位門檻電平時(shí)，其內(nèi)部單穩(wěn)電路開始工作并延時(shí)約240ms。之后，MAX810L的輸出變低，使Q1導(dǎo)通。Q1導(dǎo)通之后，MAX810L一直監(jiān)測(cè)輸出電壓以確定輸出是否過流。過載將會(huì)導(dǎo)致輸出電壓下降，當(dāng)它低于MAX810L門檻電平時(shí)，MAX810L的輸出經(jīng)過20μs的延遲后由高變低，從而關(guān)斷Q1并使負(fù)載斷開。由于MAX668的升壓作用，MAX810電源端電壓又會(huì)高于其門檻電平，240ms的復(fù)位延遲時(shí)間后，MAX810L輸出再次由高變低。
