So it is an important research in the field of the electronic technology to reduce the loss caused by the switching device and to improve the efficiency of high frequency power converters. this paper primarily focuses on the optimization of the mosfet parasitic capacitance so as to reduce the switching loss and improve the efficiency of power transforming in converters using mosfet as switch
通過分析mosfet器件的開關特性，根據輸出電容c _ （ oss ）給器件引進的動態損耗來確定優化器件輸出電容西安理工大學碩士學位論文l變化曲線的目標函數，運用可行方向法求解帶約束條件的最優值，確定出優化的輸出電容人變化曲線。 -
" 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」是指零電壓開關或零電流開關，它是利用諧振原理，使開關變換器的開關管電壓（或電流）按正弦（或準正弦）規律變化，當電壓過零時，使器件開通（或電流自然過零時，使器件關斷） ，實現開關損耗為零，從而提高開關頻率，減小變壓器、電感的體積。
