  1. 順向式(Forward)轉換器 指導教授：陳信助老師 學生：陳建育 楊孟佳

  2. 元件與規格設計 求出輸出電壓、最大、最小Lo電流，與輸出電壓漣波，變壓器一次測之最大電流 輸出電壓VO: 濾波電感電流ILo:

  3. 元件與規格設計 輸出電壓漣波: 磁化電感電流: 變壓器一次測電流: SW耐壓:

  4. Forward轉換器

  5. IsSpice 模擬 1.Vgs、Vo、ILo 2.VLm、ILm 3.In、Id1、Id2、Id3 4.Vgs、Vds

  6. Vgs、Vo、ILo模擬波形 主要是看輸出電壓Vo、濾波電感電流ILo(CCM) 因為模擬值是理想值沒有考慮元件損失，所以會有誤差

  7. IsSpice 模擬 1.Vgs、Vo、ILo 2.VLm、ILm 3.In、Id1、Id2、Id3 4.Vgs、Vds

  8. VLm、ILm模擬波形 DCM 看VLm可以得到伏秒平衡 由VLm跟ILm看出變壓器內部是做DCM(磁通重置)

  9. IsSpice 模擬 1.Vgs、Vo、ILo 2.VLm、ILm 3.In、Id1、Id2、Id3 4.Vgs、Vds

  10. In、Id1、Id2、Id3模擬波形 變壓器一次測最大電流

  11. IsSpice 模擬 1.Vgs、Vo、ILo 2.VLm、ILm 3.In、Id1、Id2、Id3 4.Vgs、ILm、Vds

  12. Vgs、ILm、Vds模擬波形 未磁通重置 磁通重置 可得知SW耐壓，觀察出變壓器的磁通重置
