摘要:	本文主旨是為了提高低電壓輸入時效率的提升，把PFC(Power Factor Correction)的電壓分成兩段式的操作，並採用雙變壓器方式的非對稱半橋轉換器架構來做設計。本文所指的兩段式升壓，當輸入電壓在間都將它升壓並整流到，而輸入電壓為間之電壓時均升壓並整流到，藉由理論上的推導後並把它進一步實際的製作，由實做所得的數據可明顯的知本文所提出的方法不僅能提高效率更能夠減少損失與干擾。 The purpose of this thesis is to improve the efficiency of the converter to improve the low-voltage, it will be divided the voltage of PFC into two sections with two stage input voltage. Using asymmetrical half bridge converter, which adopt one pair of transformer structure. When the input voltage is between ( and ), we boost it to , and when the input the voltage is between ( and ) we boost it to . The experimental results of the real implemented hardware obvious by demonstrate that the method can not only raise the efficiency but also reduce the losses of the converter.
