zero-deflection method
解釋
零偏移法-
A topology of asymmetrical half bridge soft switching is researched in this thesis, which has inherent zero voltage switching ( zvs ) capability and thus potentially higher efficiency by its resonating of the leakage of power transformer with the parasitic capacitances of the power mosft switches, whereas it does n ' t raise the expense of the converter these studies in the thesis have been done as follows : ( 1 ) the topology of asymmetrical half bridge is introduced, and its principle and the relation of duty cycle and input voltage and output voltage discussed, the method of eliminating the deflection magnetism is also brought forward
雖然，軟開關技術能夠實現功率變換器的小型化、模塊化等，但是，電路變得更加復雜，使得中小功率的變換器的成本增加，往往不利於商業競爭。本文研究了一種零電壓的不對稱半橋拓撲結構，它可以在不增加電路成本的基礎上，利用電路自身的特點，實現軟開關。本文所做的主要工作如下： （ 1 ）對不對稱半橋主電路工作原理進行分析，給出了占空比與輸出電壓、輸入電壓的關系以及消除變壓器偏磁的方法。
