本人最近使用PExprt磁性元件設(shè)計軟件進行單端正激變壓器或電感設(shè)計,雖然軟件使用簡單,應(yīng)該說已經(jīng)基本掌握其使用,關(guān)鍵是我后期要使用PSPICE Model進行DC/DC全電路仿真,在調(diào)用該model設(shè)計的時候發(fā)現(xiàn)電路根本不收斂,不知道有沒有高人曾經(jīng)這樣做過DC/DC全電路仿真,有的話請幫下我,說明一下您的建模過程,以及在PSPICE中調(diào)用是如何解決該問題,并保證設(shè)計的參數(shù)是正確的.謝謝!!!

以下為本人建立的PSPICE模型參數(shù)(刪除了部分熱損耗模型參數(shù)):
