zero current switch造句
例句與造句
- In chapter 5 , the controller of resonant converter designed by myself , was introduced , in which zero current switching ( zcs ) had been realized
第五章介紹了自行設(shè)計的適合于不同諧振頻率的諧振變換器的控制器，實現(xiàn)了變換器的軟開關(guān)技術(shù)。 - The principle and application of zero current switching boost pfc circuit are given . by introducing the development of ac / dc module with pfc the key techniques of the module are stressed on the engineering design . some problems are resolved such as the module is so small that spread the hot difficulty
從理論上分析和研究了零電流開關(guān)升壓式pfc電路的原理和應(yīng)用，并結(jié)合250w帶pfc電路ac dc模塊的研制，從工程設(shè)計角度重點闡述了該模塊的關(guān)鍵技術(shù)，解決了模塊體積小、散熱困難及工藝等方面的難題。 - " soft switching " is zero voltage switching or zero current switching , which the voltage ( or current ) of the switch varies by law of sine or quasi sine , the switch is on when its voltage reaches zero ( or switch is off when its current reaches zero ) by resonance . it makes switch loss is zero , so it can increase the operating frequency and raise power density , minimize the size of transformer and inductor
“軟開關(guān)”是指零電壓開關(guān)或零電流開關(guān)，它是利用諧振原理，使開關(guān)變換器的開關(guān)管電壓(或電流)按正弦(或準(zhǔn)正弦)規(guī)律變化，當(dāng)電壓過零時，使器件開通(或電流自然過零時，使器件關(guān)斷) ，實現(xiàn)開關(guān)損耗為零，從而提高開關(guān)頻率，減小變壓器、電感的體積。 - It's difficult to find zero current switch in a sentence. 用zero current switch造句挺難的
