，因此國(guó)外各大開關(guān)電源制造商都致力于同步開發(fā)新型高智能化的元器件，特別是改善二次整流器件的損耗，并在功率鐵氧體材料上加大科技創(chuàng)新，以提高在高頻率和較大磁通密度（Bs)下獲得高的磁性能，而電容器的小型化也是一項(xiàng)關(guān)鍵技術(shù)。SMT技術(shù)的應(yīng)用使得開關(guān)電源取得了長(zhǎng)足的進(jìn)展，在電路板兩面布置元器件，以確保開關(guān)電源的輕、小、薄。開關(guān)電源的高頻化就必然對(duì)傳統(tǒng)的PWM開關(guān)技術(shù)進(jìn)行創(chuàng)新，實(shí)現(xiàn)ZVS、ZCS的軟開關(guān)技術(shù)已成為開關(guān)電源的主流技術(shù)，并大幅提高了開關(guān)電源的工作效率。對(duì)于高可靠性指標(biāo)，美國(guó)的開關(guān)電源生產(chǎn)商通過降低運(yùn)行電流，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。
